MCAT Full-Length Answer Explanations Spreadsheet: Free AAMC and Third-Party Review Tool

Taking an MCAT full-length practice exam gives you a score, but I think the much more valuable part begins after the test is over. A seven-hour exam gives you hundreds of examples of how you think under pressure, which content areas are still weak, which answer choices repeatedly fool you, and whether your mistakes are coming from missing knowledge, passage interpretation, timing, calculations, or simply rushing. If you only look at the score and move on to the next test, you leave a huge amount of useful information behind.

The MCAT Explanations for Every Answer Spreadsheet is a large, community-built review resource that was created to make that review process easier. It contains student-written explanations and notes for thousands of questions from AAMC resources and older third-party MCAT full-lengths, with many rows explaining not only why the correct answer works but also why the other answer choices do not.

The original Reddit discussion where the project was shared is available here:

Original Explanations for Every Answer Spreadsheet Reddit Thread

There is one important thing I want you to understand before using it in 2026. This spreadsheet is not an official AAMC resource, it is not completely current, and it should not replace the explanations inside the AAMC materials you purchase or access through the Official Prep Hub. The current spreadsheet identifies itself as the June 5, 2023 version, and its AAMC table of contents was created before the current Practice Exams 5 and 6 existed under their present names.

That limitation does not mean I would ignore the spreadsheet. I would simply use it for the job it is still particularly good at: giving you another way to understand difficult questions, especially when the official explanation did not click immediately.

I did not create this spreadsheet, and I want to be clear about that because much of the work belongs to the r/MCAT community members who spent years contributing explanations. My value in this guide is showing you how I would use that resource based on the full-length review process I personally used while preparing for my MCAT.

During my own preparation, I completed five Blueprint full-length exams, used UWorld extensively for daily question practice, and later transitioned toward AAMC Question Packs, Section Banks, and official practice exams. At one point, my routine was to take a full-length on Friday and spend essentially all of Saturday reviewing it. I learned that the review day was often just as valuable as the testing day because the practice exam told me where I was, while the review showed me how I could improve before the next one.

That is exactly where I think a resource like this spreadsheet fits.

Free MCAT Full-Length Answer Explanations Spreadsheet

You can access the community spreadsheet here:

MCAT Explanations for Every Full-Length Exam Answer Spreadsheet

The file is currently titled 2023.06.05 MCAT Explanations, which is useful to know because the date immediately tells us that this is an older community snapshot rather than a continuously updated official 2026 AAMC product.

The spreadsheet’s own preface describes the project as an aggregate of notes intended to streamline the MCAT review process. Contributors were encouraged to explain the reasoning behind answers rather than simply write something such as “use the equation from the passage,” with the goal of showing calculations, identifying question pathologies, and explaining relevant content so another student could actually understand where their reasoning went wrong.

That philosophy is what makes the spreadsheet valuable to me. A useful explanation should teach you something you can carry into the next question rather than simply tell you that B was correct.

Who Made the MCAT Explanations Spreadsheet?

This is a community-created project rather than an AspiringMD resource I personally created. The spreadsheet originated within the MCAT community and was shared through r/MCAT, with many students contributing explanations, corrections, diagrams, calculations, and resources over time. The sheet itself credits contributors and explains that users were encouraged to improve unclear explanations rather than simply delete another person’s work.

You can read the original discussion here:

Explanations for Every Answer Spreadsheet on r/MCAT

I think giving that attribution is important. I am organizing the resource here because it can still be helpful for MCAT students, but the enormous amount of work inside the spreadsheet belongs to the students who built and maintained it.

What Is Actually Inside the Spreadsheet?

The spreadsheet is much larger than a simple list of AAMC answers. Its table of contents includes AAMC material, Examkrackers exams, NextStep material that predates the Blueprint rebrand, Kaplan exams, Altius exams, general study resources, charts, images, and blank spaces where contributors could build additional explanations.

For the AAMC material, the June 2023 version includes sections for the Unscored Sample Test, Practice Exams 1 through 4, Section Bank material, Question Packs, older Official Guide questions, and additional official resources that existed when the spreadsheet was being actively organized.

For third-party resources, the table of contents includes older Examkrackers full-lengths, NextStep diagnostic and practice exams, Kaplan diagnostic and full-length exams, and Altius diagnostic and practice exams.

Within individual sections, contributors could include the question location, major concept, explanation of the correct answer, explanations of wrong answers, calculations, links to useful resources, diagrams, and other notes that helped clarify the question.

That makes the document feel less like an answer key and more like a giant shared review notebook.

An Important 2026 Update: The Spreadsheet Does Not Include Every Current AAMC Exam

This is one of the biggest changes I would make to the older AspiringMD article because I do not want you opening the spreadsheet and expecting explanations for every current AAMC full-length.

The AAMC’s official practice-exam lineup has changed substantially. As of 2026, there are seven official AAMC practice exams: the free Unscored Sample Test plus Practice Exams 1 through 6. Practice Exam 1 is now free, Practice Exams 2 through 6 are the scored paid exams, and the exam previously known as the Free Practice Exam became Practice Exam 5. The AAMC also released the newer Practice Exam 6.

The community spreadsheet predates those changes. Its AAMC table of contents was built around the Sample Test and Practice Exams 1 through 4.

I would therefore not describe this as a complete 2026 explanation bank for every AAMC full-length. It is a large archive of community explanations for many important AAMC and third-party resources.

That is still extremely useful, but the distinction matters.

Does the Spreadsheet Include AAMC Practice Exams 5 and 6?

The June 2023 spreadsheet does not contain the current AAMC Practice Exams 5 and 6 as part of its original AAMC full-length structure because those products did not exist under their current lineup when this version of the spreadsheet was assembled.

Practice Exam 5 was previously called the Free Practice Exam and was later renamed and converted into a paid practice exam. Practice Exam 6 was subsequently added as a new 230-question official exam.

For those newer exams, I would use the explanations supplied directly by the AAMC inside the Official Prep platform as your primary source.

The AAMC Now Explains Every Answer Choice on Its Practice Exams

This is another reason the role of this community spreadsheet has changed since it became popular.

The AAMC currently states that all of its official Practice Exams include explanations for all answer choices in all sections, along with links to Khan Academy lessons covering related content and skills.

That means you no longer need a community spreadsheet simply because the AAMC gave you no explanation for why a distractor was wrong.

I still think alternative explanations have value, though. Sometimes you read an official explanation twice and still do not understand why your reasoning failed. A student-written explanation may describe the same concept differently, show an intermediate calculation the official explanation skipped, or point out the exact trap that caused students to choose the wrong answer.

I would use the spreadsheet as a second perspective, not as a replacement for the official explanation.

Why I Still Think This Spreadsheet Is Useful in 2026

AAMC explanations are authoritative, but authoritative does not always mean that one explanation will immediately make sense to every student. Sometimes what you need is a different way of hearing the same concept.

That is where community resources can help. Another student may explain what clue in the passage mattered, why answer C was tempting, where a calculation usually goes wrong, or why a scientifically true answer still fails to answer the actual question being asked.

The spreadsheet can also be useful for older third-party exams where explanations may be harder to locate today, particularly old NextStep, Examkrackers, Kaplan, and Altius materials represented in the workbook.

I would therefore think of the spreadsheet as a supplemental explanation archive rather than a replacement answer key.

My Personal Experience Reviewing MCAT Full-Length Exams

Full-length review became one of the most important parts of my own MCAT preparation. I eventually reached a routine where I would take a full practice exam on Friday and spend much of Saturday reviewing the exam.

I did not view Saturday as simply checking which questions I missed. I wanted to know why I missed them.

If the problem was content, I needed to figure out what information I was missing and make sure I would remember it later. If I knew the science but misinterpreted the passage, another flashcard was not necessarily going to solve the problem. If I rushed because of timing, I needed to change my pacing rather than reread another chapter.

That distinction is something I still use in medical school. When I review questions now, I want to know not only why the correct answer was correct but why I was attracted to the wrong one.

That is one reason this community spreadsheet makes sense to me even though I did not create it. Its structure encourages exactly the kind of detailed answer-choice review I found valuable.

My Experience With Blueprint Full-Lengths

Blueprint was the third-party MCAT company I used most extensively. I started with its diagnostic and eventually purchased and completed five Blueprint full-length exams.

I personally found the Blueprint exams challenging, and I thought the detailed explanations were one of their stronger features. They helped me determine whether a mistake came from content, passage interpretation, calculations, or the way I understood the question.

The community spreadsheet still uses the older NextStep name because it predates the Blueprint branding that students are more familiar with today. Its table of contents includes a NextStep diagnostic and several NextStep practice exams.

If you are using modern Blueprint exams, I would use Blueprint’s current explanations first. The spreadsheet is more interesting if you have access to one of the older NextStep exams or want another perspective on a question represented there.

My complete guide to my own Blueprint experience is here:

Should I Use Blueprint for MCAT Studying?

My Experience With UWorld and Why Question Review Matters

UWorld was my primary question-bank resource during MCAT preparation, while Blueprint was more of a secondary practice source. One of the reasons I liked UWorld was that the explanations made practice itself part of content review.

If I missed a question because I did not understand a concept, I could learn from the explanation instead of simply recording that I had gotten another question wrong.

That is the mindset I would bring to this spreadsheet. The goal is not collecting thousands of explanations. The goal is letting an explanation change something about the way you answer the next question.

If you read an explanation and think, “Okay, B was right,” but cannot explain why A, C, and D failed, you probably have not finished reviewing yet.

Why I Think You Should Review Wrong Answer Choices

A multiple-choice question gives you more information than the correct answer alone.

Suppose you chose B and the correct answer was C. Obviously, you need to understand why C works. However, I also want to know why you chose B.

Did B contain a true scientific statement that did not answer the question?

Did you misremember a definition?

Did you reverse two relationships?

Did the passage explicitly contradict B and you missed the relevant sentence?

Did you eliminate C because you made an incorrect assumption?

Those questions are often where the learning happens.

The AAMC itself now provides explanations for all answer choices on its current practice exams, which reinforces the value of understanding distractors rather than focusing exclusively on the credited answer.

AAMC Student Advice Supports Reviewing Every Option

One of the AAMC’s own student preparation profiles gives advice that is remarkably similar to the approach I recommend here. The student describes getting additional value from practice exams by explaining why the correct answer works and why the other answer choices are wrong, essentially treating every multiple-choice question as several learning opportunities rather than one.

I like that approach because it prevents review from becoming passive.

You should be able to defend the correct answer and reject the distractors.

That is much closer to the decision you will actually make on test day.

How I Would Use This Spreadsheet After a Full-Length

I would first take the full-length under realistic testing conditions without opening the spreadsheet or looking at outside explanations. The practice score is useful only when the test genuinely measures what you can do independently.

After finishing the exam, I would take a break before beginning detailed review. A full-length is exhausting, and I personally preferred having a dedicated review day rather than trying to perform a seven-hour autopsy immediately after finishing seven hours of testing.

When I returned to the exam, I would begin with the official explanation provided by the testing company. For AAMC questions, the AAMC explanation should be your primary reference.

If the official explanation makes sense, great. I would still ask whether I understood why the wrong answers failed.

If I remained confused or wanted a second explanation, that is when I would open this community spreadsheet and find the corresponding test, section, and question number.

Treat Correct Guesses Like Missed Questions

One of the most important habits I would add is reviewing questions you answered correctly for the wrong reason.

If you were completely unsure between B and C and happened to select C, your score report sees a correct answer. Your future MCAT performance should not treat it as mastered.

I would flag those questions while taking the exam and include them in the same review process as actual misses.

This is especially important with AAMC questions because sometimes you can eliminate several distractors without fully understanding the underlying concept. That is useful test-taking skill, but if the content gap remains, it can appear again in a question where the distractors are less forgiving.

Start With Your Reasoning Before Reading Someone Else’s

Before opening the spreadsheet explanation, try to reconstruct what you were thinking during the question.

Write down why you selected your answer.

Then look at the correct answer and ask what information you failed to use.

Only after doing that would I read several paragraphs of community explanation.

If you immediately read somebody else’s reasoning, it becomes surprisingly easy to convince yourself that you “would have known that.” You lose the chance to diagnose the thought process that actually produced your answer.

I would rather see your imperfect reasoning written down first because that gives you something concrete to correct.

Separate Content Errors From Reasoning Errors

This was one of the most useful distinctions in my own studying.

A content error occurs when you genuinely do not know something you needed. Maybe you forgot the relationship between Km and competitive inhibition or could not remember an electrochemistry equation.

A reasoning error happens when you had enough information but used it incorrectly. Maybe the passage directly answered the question and you brought in outside assumptions, or you misunderstood what the experiment’s control group demonstrated.

Those mistakes require different fixes.

A content error may deserve an Anki card or targeted content review. A reasoning error may deserve a written note about the thought process you need to change.

If you treat every missed question as a content problem, your study plan eventually becomes an endless pile of flashcards without actually fixing the way you approach passages.

Separate Timing Errors Too

Some questions are missed because the concept is difficult, while others are missed because you reached the final passage with six minutes remaining and rushed through everything.

That is a different category.

If timing caused the problem, review the question so you understand it, but also address the pacing issue that created the mistake.

You may need to spend less time rereading difficult passages, become faster at recognizing when to move on, improve your calculations, or stop allowing one question to consume four minutes because you are determined to solve it before continuing.

A good error log should make timing problems visible rather than hiding them inside a generic “wrong question” category.

Separate Careless Errors From Knowledge Gaps

I would also track mistakes such as reading “NOT” as “is,” overlooking a unit conversion, changing a correct answer without a good reason, or selecting a choice that directly contradicts something you already recognized.

These feel frustrating because you may understand the content completely.

The solution is usually not rereading an entire chapter.

Instead, look for patterns. If careless mistakes appear consistently late in sections, fatigue or pacing may be part of the issue. If you regularly miss negative wording, create a habit of consciously identifying words such as NOT, EXCEPT, LEAST, and MOST before evaluating the answer choices.

The spreadsheet can help explain the question, but you still need to diagnose the behavior that created your mistake.

How I Would Review AAMC Questions With the Spreadsheet

For AAMC material, I would use the following hierarchy:

First, use the official AAMC explanation. The current official practice exams include explanations for all answer choices, and those explanations come directly from the organization responsible for the exam.

Second, explain the question to yourself. If you cannot put the reasoning into your own words, you may not fully understand it yet.

Third, use the community spreadsheet if you still need another perspective. A student explanation may clarify a calculation, passage detail, or distractor in a way that resonates more naturally with you.

Finally, verify questionable factual claims. Community explanations can be useful without being authoritative, and the spreadsheet itself was designed to allow community editing and correction.

That order gives you the benefit of the community resource without placing it above the primary source.

How I Would Review Blueprint or Other Third-Party Exams

For a modern third-party exam, I would begin with the explanation supplied by that company. If you paid for the exam, you should take advantage of the explanation system that came with it.

This spreadsheet becomes especially useful for older third-party resources represented in the table of contents, including Examkrackers, NextStep, older Kaplan exams, and Altius exams.

Because the workbook is an older snapshot, question numbering and exam versions may not match modern commercial products perfectly. I would verify that you are looking at the same test before assuming an explanation corresponds to your question.

Do Not Use the Spreadsheet Before Taking the Exam

I would strongly avoid browsing the answer tabs before you complete the corresponding practice material.

Once you see an answer or explanation, that question loses much of its diagnostic value.

You may not consciously remember the exact answer later, but even recognizing a passage, diagram, or explanation can influence your reasoning.

Take the exam first.

Then use the spreadsheet.

This is especially important for AAMC material because there are a limited number of official practice questions, and you want your first exposure to give you the best possible measurement of how you would reason independently.

Do Not Use It as a Substitute for Owning AAMC Materials

The spreadsheet should be used alongside questions you legitimately have access to.

It is an explanation and review resource, not a substitute for obtaining the corresponding AAMC or third-party practice materials.

That was already an important principle in the existing AspiringMD page, and I would keep it prominent because it also makes the article more trustworthy.

For current official AAMC products, you can see the available practice exams and question sets here:

AAMC Official MCAT Practice Products

How I Would Turn a Missed Question Into an Anki Card

Anki was an important part of my own MCAT preparation, with MileDown serving as my main deck and some JackSparrow added when I wanted additional detail.

I would not turn the entire question into a flashcard.

Instead, I would identify the smallest transferable lesson that would prevent me from making the same content mistake again.

If I missed a question because I reversed competitive and noncompetitive inhibition, the card should test that distinction rather than reproduce the passage.

If I missed a question because I forgot the function of aldosterone, make a targeted physiology card.

If the mistake was that I ignored a graph label, I probably would not make an Anki card at all because that is a reasoning or attention problem.

This keeps your deck focused on knowledge that spaced repetition can actually help.

My MileDown guide is here:

MileDown MCAT Anki Deck: Free Download and My Experience

Why I Would Not Make a Card for Every Missed Question

It is tempting because making a flashcard feels like you have permanently fixed the mistake.

Sometimes you have not.

If your problem was misunderstanding the experimental design, a card saying “remember to understand experiments” is not going to help much.

If you ran out of time, a flashcard will not increase your pacing.

If you misread the question stem, another card may simply add clutter to your review workload.

I personally liked MileDown partly because the deck was manageable enough to leave time for practice. I would not destroy that advantage by adding hundreds of unnecessary cards from every full-length.

Add cards when there is something specific you need spaced repetition to help you remember.

Write a One- or Two-Sentence Takeaway

After reviewing a difficult question, I like creating a concise takeaway that captures the transferable lesson.

A useful takeaway might say: “When a passage gives both protein and mRNA data, do not assume transcription and translation changed in the same direction.”

Another might say: “If I know the equation but the units do not match the answer choice, check whether I missed a conversion before recalculating everything.”

Those sentences are much more useful than writing an entire paragraph summarizing the question because you can reread them later and immediately understand what changed about your approach.

The community spreadsheet itself was designed around this kind of explanation-based review rather than simply recording answer letters.

Build a Personal Error Log Beside the Community Spreadsheet

The community spreadsheet explains questions, but I would still keep a separate record of your own mistakes.

You need somewhere to record which exam you took, which question you missed, why you missed it, what content category was involved, and what you are going to do differently.

I created a free error-log spreadsheet specifically for that purpose:

Free MCAT Full-Length Review & Error Log Spreadsheet

Think of the two resources as serving different jobs. The community spreadsheet helps explain the question, while your personal error log helps explain you.

That second part becomes more valuable as you accumulate practice.

Use the Spreadsheet With My MCAT Full-Length Review Template

If you prefer a more detailed system for tracking scores and missed questions, I also have a full-length review template here:

MCAT Full-Length Review Template

I would take the exam, use the official explanation and community spreadsheet during review, and then record only the high-value lessons in my own tracker.

You do not need to copy every explanation into your personal spreadsheet. The point is extracting what you need from the question.

That keeps your tracker readable several weeks later.

Use It With the MCAT Full-Length Tracker

If you mainly want to track score trends across several tests rather than maintain a detailed explanation database, I also made a simpler score and wrong-answer tracker:

MCAT Full-Length Tracker Spreadsheet

This can help you see whether your total score and section scores are moving in the right direction while the explanation spreadsheet handles individual questions.

I think separating score tracking from explanation review can be useful because otherwise one spreadsheet eventually becomes enormous and difficult to navigate.

The Spreadsheet Can Help You Identify Recurring Distractor Patterns

One of the most useful things you can learn from reviewing wrong answers is why certain distractors keep working on you.

Maybe you repeatedly select answers that are scientifically correct but not supported by the passage.

Maybe you choose an answer that reverses cause and effect.

Maybe you select the variable the experiment changed when the question asked what was measured.

Maybe CARS answers that sound sophisticated consistently pull you away from the more directly supported choice.

The answer-choice explanations inside a resource like this can help you see those patterns because you are repeatedly asking what makes each distractor attractive and what ultimately makes it wrong.

That skill transfers from one question to another much better than memorizing the answer to a single passage.

Do Not Memorize AAMC Answer Choices

As you review more AAMC material, you may begin remembering specific passages or answer choices.

That is normal.

What I would avoid is turning review into memorization of those answers.

If you retake an exam later and immediately remember that question 23 was C, force yourself to explain why C is correct and why the other three answers fail.

An AAMC student preparation profile makes a similar point, describing retaken questions as opportunities to explain why each incorrect answer is wrong even when the correct choice is already familiar.

That makes repeat exposure much more educational.

What If the Community Explanation Disagrees With the AAMC?

I would use the AAMC explanation.

The spreadsheet is community-created and was intentionally designed so contributors could edit and improve explanations. That collaborative structure is useful, but it also means individual explanations should not be treated as official MCAT doctrine.

If you find a disagreement, compare the AAMC explanation with the passage and question itself.

If the dispute involves a science concept, verify it with a trusted content source.

Community explanations are most valuable when they clarify the official reasoning, not when they replace it.

What If Two Community Explanations Disagree?

That can actually become a useful exercise.

Ask what evidence in the passage supports each interpretation.

Then ask what the question stem is specifically requesting.

The best explanation should connect the passage, stem, and answer choice without adding unsupported assumptions.

If the disagreement cannot be resolved confidently, go back to the official explanation or a reliable science source rather than spending an hour debating anonymous comments.

Your goal is learning the reasoning you can use on future questions, not winning an argument over one old practice item.

What About CARS Explanations?

I would be particularly cautious about allowing somebody else’s CARS reasoning to completely replace your own.

CARS is different from a factual Biology question because the central issue is often how the passage supports a conclusion rather than whether you remembered a scientific fact.

I would first explain why I chose my answer and identify the exact sentence or argument I thought supported it.

Then I would compare that reasoning with the correct answer.

A community explanation can help show where you overreached, missed a tone shift, or selected something that sounded reasonable but was less directly supported.

I would not create a giant Anki deck of specific CARS answers because the goal is improving the reasoning process, not remembering old passages.

What About Questions You Got Right Confidently?

You do not have to spend ten minutes reviewing every easy correct question simply because the spreadsheet contains an explanation.

Your time matters.

If you answered confidently, understood why the correct choice worked, and can quickly explain why the alternatives fail, I would move on.

I would spend my deepest review time on incorrect answers, correct guesses, questions where I was uncertain, and questions that exposed a concept I know tends to cause trouble.

That makes detailed review sustainable even when you are taking full-lengths regularly.

My Friday Full-Length and Saturday Review Routine

One of the things I liked about having separate testing and review days was that it gave each task enough attention.

Friday was about performing.

Saturday was about learning.

That prevented me from finishing a long exam, seeing my score, and immediately rushing through explanations because I was tired and wanted to be done.

If your schedule allows it, I would still recommend protecting a meaningful block of time for review after each full-length. It does not have to be Saturday, and it does not have to take exactly the same number of hours every week.

The important part is treating review as a scheduled part of your study plan rather than something you will do “if there is time.”

How Long Should Full-Length Review Take?

There is no universal number, but I would expect detailed review to take several hours.

If you missed very few questions and were confident on most of the test, the review may be much faster.

If you had dozens of misses, uncertain guesses, timing problems, and several content gaps, the review can easily consume much of a day.

I would rather see a student spend enough time to understand one full-length than race through the explanations so they can say they took another practice exam two days later.

The value comes from closing gaps between tests.

How Many Full-Lengths Should You Review This Deeply?

Ideally, I would apply the method to every important full-length, although the depth can vary.

Your earliest diagnostic may generate so many content gaps that reviewing every subtle distractor is not the best use of twelve hours.

Later exams become much more valuable for detailed review because you have enough content knowledge to distinguish between isolated weaknesses and reasoning patterns.

As your exam approaches, I would review AAMC full-lengths particularly carefully because those questions most closely reflect the reasoning style you need to understand.

Use the Spreadsheet After Section Bank Questions Too

The community spreadsheet includes Section Bank material in addition to full-length exams.

I would absolutely use the same review principles there.

The Section Banks can expose difficult experimental reasoning and content application without requiring a complete seven-hour exam.

If you repeatedly struggle with a particular type of Section Bank question, compare explanations, identify the underlying skill, and record the pattern in your personal error log.

Then look for whether the same problem appears on your next full-length.

Use It After AAMC Question Packs Carefully

The spreadsheet also includes AAMC Question Pack material.

These questions can still be useful for content and reasoning practice, but remember that the different AAMC resources were created for somewhat different purposes and may vary in difficulty or style.

I would focus less on trying to derive a predicted MCAT score from Question Pack performance and more on learning from the questions themselves.

If you miss a Physics Question Pack problem because of an equation you forgot, fix the equation.

If you miss a CARS passage because you repeatedly choose answers that go beyond the author’s claims, fix that reasoning pattern.

What Resources Are Missing From the Spreadsheet?

The most important missing current resources are the newer AAMC Practice Exams 5 and 6 under the current 2026 lineup.

The workbook also obviously cannot be expected to perfectly mirror every modern version of every third-party company’s exam bank because commercial products have changed since the spreadsheet’s 2023 snapshot.

That is why I would not market this page as literally containing every MCAT explanation currently available.

The more accurate description is a large free archive of community explanations for many AAMC and older third-party MCAT questions.

Accuracy in that description matters more to me than making the resource sound larger than it actually is.

Is the Spreadsheet Still Worth Using if AAMC Already Gives Explanations?

I think so, but its value is different now.

When a primary explanation completely answers your question, you probably do not need another explanation simply for the sake of reading one.

When the official explanation feels too short, skips a calculation you do not understand, or does not address why you found a distractor so appealing, the community spreadsheet becomes much more valuable.

It also gives you access to years of student reasoning around older resources.

I would therefore use it selectively rather than opening it automatically for every question.

Is This Better Than Reddit Explanations?

The spreadsheet’s main advantage over manually searching Reddit is organization.

Instead of searching the question number and reading several unrelated threads, you can often go directly to the appropriate exam and section.

Reddit still has value because a specific question may have a long discussion with multiple ways of solving it.

I would start with the organized spreadsheet when the question is represented there and search the broader community only when I still need clarification.

Is It Better Than the Official AAMC Explanations?

No. I would not rank a community explanation archive above the official AAMC explanation for an AAMC question.

I would use them together.

The AAMC explanation tells you how the organization responsible for the question explains the answer, while the spreadsheet may give you another student’s way of reaching the same conclusion.

That combination can be helpful when one explanation alone does not click.

What I Would Do When an Explanation Is Too Complicated

Sometimes a community explanation becomes longer and more detailed than the knowledge the question actually required.

When that happens, return to the question.

Ask what information was actually necessary to choose the answer.

Then write a shorter explanation in your own words.

You do not have to memorize every scientific detail somebody added to a shared spreadsheet simply because the information is interesting.

The MCAT already contains enough content without turning every missed question into a graduate seminar.

How to Know When You Have Finished Reviewing a Question

I consider a question reviewed when you can answer four things clearly: why the correct answer is correct, why your answer was wrong, what caused you to make that mistake, and what you will do differently if a similar question appears again.

That final question is the important one.

If your conclusion is simply “I will get it right next time,” you have not really created a plan.

If your conclusion is “I need to learn the difference between aldosterone and ADH, so I am adding one comparison card to Anki,” you have an actionable content fix.

If your conclusion is “I ignored the graph and answered from memory, so I need to force myself to interpret the figure before looking at the choices,” you have an actionable reasoning fix.

How I Would Use the Spreadsheet During the Final Month

During the final month, I would increasingly prioritize AAMC material and review it deeply.

Because the current AAMC practice exams already provide answer-choice explanations, I would begin there.

I would use the community spreadsheet selectively for older exams it covers and for AAMC questions where I wanted an additional explanation.

My personal error log would become more important than reading every explanation in the spreadsheet because by that point I should have a growing record of the specific mistakes I repeatedly make.

The final month should become increasingly personalized around your weaknesses.

How I Would Use It During the Final Week

I would not spend the final week rereading thousands of old community explanations.

At that stage, I would review my personal high-yield mistakes, important Anki cards, recurring content gaps, and reasoning patterns that appeared across several exams.

The giant spreadsheet is most useful during the process of creating those insights.

Once you have extracted the lesson, you do not need to continually return to the original question.

That is one reason I recommend writing concise takeaways during review.

Do You Need to Copy the Spreadsheet?

The Google Sheet is view-only in its main shared form, and the file itself provides downloadable or backup options because Google Sheets historically limited how many simultaneous users could access the resource.

You do not necessarily need to copy the entire giant workbook into your Drive if your only goal is reading explanations.

I would keep your own notes and error log separate because personalizing an enormous community spreadsheet can become unwieldy.

If you do download a copy, remember that your version will not automatically inherit future community changes.

Frequently Asked Questions About the MCAT Answer Explanations Spreadsheet

Where can I access the MCAT Explanations for Every Answer Spreadsheet?

You can open the current shared file here:

MCAT Full-Length Answer Explanations Spreadsheet

The file currently identifies itself as the June 5, 2023 MCAT Explanations version.

Is the spreadsheet free?

Yes. The spreadsheet was built as a free community resource, and its own notes describe a goal of keeping the project publicly accessible without a paywall.

You will still need legitimate access to the corresponding AAMC or third-party questions because this resource is intended to help you review them rather than replace the underlying practice material.

Did AspiringMD create the spreadsheet?

No. I did not create the spreadsheet. It originated as a community project associated with r/MCAT, and credit belongs to the contributors who built and refined the explanations over the years.

I am sharing it here and explaining how I think it can fit into a modern MCAT review system.

Is the spreadsheet official AAMC material?

No. It is community-created.

For AAMC questions, I would use the official AAMC explanations first and treat this spreadsheet as an additional perspective.

Does it include explanations for every AAMC full-length?

No, not under the current 2026 AAMC lineup. The spreadsheet predates the current Practice Exams 5 and 6 and contains the older Sample Test and Practice Exams 1 through 4 structure.

I would not call it a complete explanation bank for all seven current AAMC practice exams.

How many AAMC full-length practice exams are there now?

The AAMC currently has seven official practice exams in total: the free Unscored Sample Test and Practice Exams 1 through 6. Two are free, while five are currently sold as low-cost practice exams.

Does AAMC Practice Exam 5 appear in the spreadsheet?

Not as the current Practice Exam 5 under the spreadsheet’s original AAMC full-length structure. Practice Exam 5 was previously called the Free Practice Exam and was renamed after this spreadsheet snapshot was created.

Does it include AAMC Practice Exam 6?

The June 2023 spreadsheet predates Practice Exam 6, so I would use the AAMC’s own current explanations for that exam.

Does the spreadsheet include the AAMC Section Bank?

Yes. The table of contents includes Section Bank material for C/P, B/B, and P/S.

Does it include AAMC Question Packs?

Yes. The spreadsheet includes Question Pack sections for Chemistry, Physics, CARS, and Biology material.

Does it include Blueprint exams?

The spreadsheet contains NextStep material, including a diagnostic and several full-lengths. NextStep is the older branding associated with what students now know as Blueprint, so you should verify that the exact exam and question numbering match your resource before using an explanation.

Does it include Kaplan exams?

Yes. The workbook’s table of contents contains an older Kaplan diagnostic and multiple Kaplan full-length sections.

Modern Kaplan products may not correspond exactly to those older exams, so match the question carefully.

Does it include Altius exams?

Yes. The table of contents includes an Altius diagnostic and several Altius full-lengths.

Does it include Examkrackers?

Yes. Examkrackers practice full-lengths are represented in the workbook.

Are the community explanations always correct?

I would not assume that. The spreadsheet was collaboratively edited, and its creators explicitly encouraged contributors to correct unclear or inaccurate explanations.

For AAMC questions, use the official explanation as the primary source. Verify science claims with reliable content sources when something appears questionable.

Do current AAMC exams already explain wrong answers?

Yes. The AAMC currently states that its official Practice Exams include explanations for all answer choices in all sections.

That means the community spreadsheet is best thought of as an alternative explanation source rather than the only way to understand wrong answer choices.

Should I review questions I answered correctly?

I would review correct questions when you guessed, were uncertain, or used incorrect reasoning. A lucky correct answer can reveal the same weakness as an actual miss.

If you were confident, your reasoning was correct, and you understand why the distractors fail, I would move on rather than reviewing every easy question for the sake of completeness.

Should I review every wrong answer choice?

For difficult or important questions, I think this can be extremely valuable. Understanding why the distractors fail helps you recognize common traps and distinguish concepts that look similar.

The AAMC itself now provides answer-choice explanations on its practice exams, and an AAMC student profile specifically recommends reasoning through why each wrong option is wrong as a way to get more learning from practice.

Should I make Anki cards from the explanations?

I would make Anki cards from transferable content gaps, not from every question.

Anki was a major part of my own MCAT preparation, and I primarily used MileDown because its manageable workload still left enough time for practice questions and full-length review.

If the mistake was reasoning, pacing, or careless reading, I would usually record the lesson in my error log rather than creating another flashcard.

How long should reviewing an MCAT full-length take?

There is no exact number. I personally sometimes spent most of the following day reviewing a full-length.

The review should take long enough that you understand your meaningful misses and uncertain questions, but you do not need to spend ten minutes rereading an explanation for every question you answered confidently and understood correctly.

Is this spreadsheet better than an MCAT error log?

They do different things.

This community spreadsheet helps explain the questions. Your error log helps identify patterns in your own mistakes.

I would use both together rather than choosing between them.

Where can I get a free MCAT error log?

I created one here:

Free MCAT Full-Length Review & Error Log Spreadsheet

You can use the community explanation spreadsheet to understand difficult questions and then record only the most important personal lessons in your own error log.

Final Thoughts: Is the MCAT Explanations Spreadsheet Still Worth Using in 2026?

I think it is still a very useful resource, but I would describe it differently today than I would have several years ago.

The spreadsheet is not a complete 2026 answer bank. It is a large community archive whose current shared version dates to June 2023, and the AAMC has since expanded and reorganized its official practice-exam lineup. The AAMC now provides explanations for every answer choice on its current Practice Exams, which means you no longer need a community spreadsheet simply to understand why an official distractor was wrong.

What the spreadsheet still gives you is another perspective.

Sometimes the official explanation makes immediate sense and you can move on. Sometimes you need somebody to show the missing calculation, explain why the tempting answer was attractive, or describe the concept in a different way before it finally clicks.

That is where I would use it.

My own MCAT experience made me a strong believer in detailed question review. I completed five Blueprint full-lengths, used UWorld extensively, transitioned to AAMC practice later, and had periods where Friday was my testing day and Saturday was essentially devoted to reviewing what happened.

That review process taught me that a missed question is not one problem. It can represent several completely different problems, and figuring out which one occurred is what determines whether your next week of studying actually makes you better.

If I forgot a fact, I could review the content or add a focused Anki card. If I misunderstood an experiment, I needed to work on experimental reasoning. If I ran out of time, I needed to address pacing. If I picked a tempting answer that the passage did not support, I needed to understand why that trap worked on me.

The community spreadsheet can help with the first part of that process by giving you another explanation of the question. Your job is to take the explanation one step further and ask what it tells you about your own thinking.

I would therefore use the resource in a simple order. Take the exam honestly, review the official explanation first, try to explain the question yourself, open the community spreadsheet when you want another perspective, and then record the smallest useful lesson in your personal error log or Anki deck.

That process is much more valuable than reading thousands of explanations because they happen to be available.

The goal is not to collect more spreadsheets. The goal is to make sure every full-length you take teaches you enough that you are a little harder to fool on the next one.
