Is September Too Late to Take the MCAT for This Cycle?

If you are planning to apply to medical school this cycle and your MCAT has been pushed into September, I would consider that very late for most MD applicants, primarily because you are not just dealing with the September test date. You also have to account for the month it takes to receive your score, which means a September MCAT may not become available to medical schools until October.

That does not mean taking the MCAT in September makes acceptance impossible. Your situation is much more favorable if your AMCAS application is already submitted and verified, your secondary essays are finished or nearly finished, and the MCAT is the only major item preventing schools from reviewing you. Someone who still needs to take the MCAT, submit AMCAS, wait for verification, receive secondaries, and complete those applications is facing a much more difficult timeline.

For most applicants considering a September MCAT for the current MD application cycle, I would therefore look at when the score will be released, what your medical schools do with applications that are awaiting an MCAT score, how prepared you actually are for the exam, and whether protecting this cycle is worth risking a lower MCAT score.

Is a September MCAT Too Late for Medical School Applications?

For the traditional MD application cycle, a September MCAT is late enough that I would approach it cautiously. The MCAT itself is offered through September, but the fact that the AAMC offers a test date does not mean that date is equally competitive for someone applying during the same admissions cycle.

According to the AAMC’s official 2026 MCAT testing calendar and score release schedule, the timing for the final U.S. MCAT dates of 2026 looks like this:

MCAT test date	Score release date
September 3, 2026	October 6, 2026
September 4, 2026	October 6, 2026
September 11, 2026	October 13, 2026
September 12, 2026	October 13, 2026

The AAMC explains that official MCAT scores generally take approximately 30 to 35 days to be released because of the scoring and review process. That means an applicant taking the MCAT on September 12 is not really adding a September MCAT score to their application. They are adding an October 13 MCAT score.

For schools that will not consider your application complete or ready for review until your new MCAT score is available, that difference can push meaningful review into October.

The Score Release Date Matters More Than the Test Date

One of the easiest ways to underestimate the impact of a September MCAT is to look only at the day you sit for the exam. Medical schools cannot evaluate a score that has not been released yet, and the AAMC does not provide an unofficial score immediately after the test.

If you take the September 3 MCAT, your score is scheduled for October 6. If you take the September 12 MCAT, your score is scheduled for October 13.

By those dates, many applicants have already been complete at medical schools for weeks or months. Interview invitations are already being distributed at many programs, and some schools using rolling admissions have been reviewing applications since the summer.

This does not mean every interview spot is gone by October, because medical schools continue interviewing well beyond that point. It does mean your application may enter the review process substantially later than it would have with a spring or early-summer MCAT.

That timing is why my broader guide on when to start studying for the MCAT and when to take it generally recommends planning the exam early enough that your score does not become the part of your application holding everything else back.

September MCAT Timing Depends on How Far Along Your Application Already Is

I would evaluate a September MCAT very differently depending on what the rest of your application looks like.

Your situation	How I would view a September MCAT
Primary already verified, secondaries submitted, waiting only for MCAT	Late, but potentially viable at selected schools
Primary verified, secondaries mostly prewritten	Late, but you can minimize additional delays
Primary submitted but still awaiting verification	Increasingly difficult
Primary not yet submitted	Very late for most MD applicants
September MCAT is a retake and schools already have an earlier score	Highly school- and score-dependent
Applying primarily DO	Potentially more viable, but still requires school-specific research

An applicant who submitted AMCAS early, became verified, completed their secondary applications, and is simply waiting for an October MCAT score has already eliminated several other sources of delay.

An applicant who takes the MCAT in September and then waits until October to decide whether to submit AMCAS is creating delays in sequence rather than allowing them to happen simultaneously. Verification, secondary applications, school-specific requirements, and eventual application review can then move the timeline even further into the fall.

Can You Submit AMCAS Before Taking the MCAT in September?

Yes. You do not need to wait for your MCAT score before submitting AMCAS.

AMCAS can process and verify an application without an available MCAT score. Your recent MCAT score will later become part of your AMCAS record after it is officially released.

I have a full guide on submitting AMCAS without an MCAT score because this is one of the situations where understanding the difference between AMCAS verification and medical-school review can save you a significant amount of time.

This is also something I did during my own application cycle. I took my MCAT during the first week of May and submitted my AMCAS primary three days after AMCAS opened for submission, before my MCAT score had been released. That allowed my primary application to begin moving through the process rather than waiting for my MCAT result before I even entered the AMCAS queue.

My timing was obviously much earlier than a September MCAT, but the principle is useful for a late tester. If your primary application is ready, waiting until October for your MCAT score and then beginning AMCAS may create an additional delay that was avoidable.

Will Medical Schools Review Your Application Without Your September MCAT Score?

This depends on the medical school.

AMCAS verification and an individual medical school’s definition of a complete application are not the same thing. A school may already have your verified primary application while still waiting for your MCAT score before placing your file into full admissions review.

Some schools may also use MCAT information when deciding whether to send a secondary application. Others send secondaries broadly and allow you to complete the supplemental application while they wait for your test score.

I discuss those differences in my guide on whether medical schools send secondaries to everyone or screen applicants first. A missing MCAT can be particularly relevant at schools that use academic thresholds or conduct a substantive primary screen before sending their secondary.

Before relying on a September MCAT, I would check every school on your list individually. Look for the latest MCAT date the school accepts, whether it will review an application with a pending future MCAT, and whether an existing score may be used while the admissions committee waits for your retake.

What Does Student Doctor Network Say About Taking the MCAT in September?

For this article, I searched Student Doctor Network (SDN) specifically for discussions about taking the MCAT in September while applying during the same medical school admissions cycle. I looked through multiple discussions, including questions from applicants who were already verified and waiting only on a September MCAT, and summarized the recurring advice rather than relying on a single forum response.

The SDN consensus is generally quite cautious about a September MCAT for MD applicants. Commenters repeatedly point out that the problem is not simply taking the exam in September; it is that the score may not arrive until October, which can prevent the application from becoming complete at schools that are waiting for the new score.

In one discussion about an early-September MCAT, the applicant had already submitted and verified the primary application but had been forced to move the MCAT because of health circumstances. The advice was still that an MCAT delaying completion until later in the cycle could create a disadvantage at some schools. In another discussion involving a September MCAT and the Texas application cycle, an SDN admissions contributor recommended waiting for the following cycle rather than building a strategy around receiving an MCAT score immediately before a late application deadline.

SDN discussions also tend to become more favorable when the applicant is talking about certain DO schools rather than MD programs, although the advice still depends heavily on the applicant’s existing GPA, MCAT history, school list, and how much of the application has already been completed. I would not use an old forum anecdote to decide whether a particular school accepts a September MCAT because those policies can change, but the recurring SDN concern about an October completion date remains very relevant.

What Does Reddit and r/premed Say About Taking a September MCAT?

I separately searched Reddit, particularly r/premed, for discussions from applicants considering a September MCAT for the same application cycle. I reviewed multiple threads and summarized the recurring themes rather than treating one applicant’s eventual outcome as evidence for everyone.

The r/premed advice is also cautious, but the conversations tend to place more emphasis on how much of the application is already finished. Applicants whose primaries are verified and whose secondary essays are already completed or prewritten are generally viewed more favorably than applicants planning to wait for the September MCAT score before beginning the rest of the application.

One recent r/premed discussion involved an applicant planning a September retake after already submitting a primary. Commenters advised against adding additional schools or submitting further secondaries based on a very low existing score until the new MCAT result was available. That advice reflects another complication with September retakes: medical schools may already see and potentially act on your existing score while you wait for the new one.

Another r/premed discussion about late MCAT dates included applicants noting that some schools accept September test dates, while also emphasizing the need to check individual programs rather than assuming one rule applies everywhere.

The community discussions reinforce the same conclusion I reach from the official timeline: a September MCAT is not automatically impossible, but the applicant has very little room for additional delays. Having a verified primary, completed secondary essays, realistic school list, and a score that is genuinely worth waiting for makes the strategy considerably more defensible.

What If September Is Your First MCAT Attempt?

If September will be your first MCAT attempt and you are applying during the same cycle, I would be particularly cautious because you are committing money and time to medical school applications without knowing one of the most important academic data points on your application.

Your MCAT score can substantially change which medical schools are realistic. A student expecting a 515 based on practice exams may build a very different school list from someone who ultimately scores a 503, and there is no guarantee that test day will reproduce your recent full-length average exactly.

Waiting for the score before applying broadly protects you from spending money on schools that no longer make sense, but waiting until October to begin applying makes an already-late application even later.

One possible approach for an applicant who is committed to the current cycle is submitting AMCAS earlier to begin verification while initially designating a limited number of schools, then expanding the school list after the MCAT score arrives. That strategy can reduce one timing delay, but it does not eliminate the larger problem that many of your applications may not become complete until October.

What If the September MCAT Is a Retake?

A September retake is a different situation because medical schools may already have a previous MCAT score available.

If your existing score is reasonably competitive for some of the schools on your list, those programs may be able to evaluate your application differently than they would evaluate someone with no MCAT score at all. However, you should not assume that every school will automatically hold your application until the future score arrives.

Medical schools have different policies regarding pending MCAT dates and application review. Some may wait for the new score if you indicate that another test is forthcoming, while others may begin evaluating the file with the information already available.

This creates a real risk if your current MCAT is significantly below a school’s screening threshold. A future September retake does not necessarily protect you from being screened based on the score already on your application.

I would contact individual admissions offices or review their published policies if the new score is critical to your competitiveness. The question you need answered is not merely whether they “accept September MCATs,” but whether they will hold your application for the pending score rather than evaluate the existing one first.

Should You Submit Secondaries Before Your September MCAT Score Comes Back?

If a school sends you a secondary while your September score is pending, completing it before score release can help prevent another delay after October.

For example, if you take the September 4 MCAT and receive your score October 6, having your secondary, letters, and other required materials already submitted may allow the MCAT score to become the final missing component. Waiting until October 6 to start writing every secondary could push completion several more weeks into the cycle.

I would still be selective if your existing MCAT information creates a substantial risk of being screened out or if you have no idea whether the September result will make the school realistic. Secondary fees can add up quickly, and submitting twenty supplemental applications before knowing whether your new MCAT is competitive can become expensive.

Your strategy should balance timing against uncertainty. I would prioritize secondary applications for schools you would genuinely attend and where your expected MCAT range, GPA, experiences, residency, and mission fit give you a reasonable argument for applying.

September 3 and September 12 Are Meaningfully Different

The 2026 score-release calendar illustrates why even dates within September should not be treated as identical.

A September 3 or September 4 MCAT is scheduled to release on October 6, while a September 11 or September 12 exam is scheduled to release on October 13. A difference of about one week may sound minor, but late in a rolling application cycle there is little advantage to giving away additional time unless that extra week materially improves your expected score.

I would never recommend taking September 3 instead of September 12 if your AAMC full-length scores clearly show that you are not ready. A rushed MCAT score can follow you beyond one application cycle, while an additional application year can be approached much more strategically.

The best test date is therefore not simply the earliest available date. It is the earliest date on which you are realistically prepared to earn a score that represents your ability.

Do Not Take a September MCAT Just to Save the Current Cycle

If your AAMC practice scores are substantially below the score you need, I would not sit for a September MCAT simply because it is the final chance to keep the current application plan alive.

I have firsthand experience with how much the MCAT can dominate your schedule and decision-making. During my own preparation, I used resources including AAMC materials, Jack Westin, Khan Academy, and Anki, and I learned that the usefulness of another week or another study resource depends on what your actual weaknesses are rather than how badly you want to preserve a particular date on the calendar.

Your full-length practice tests should have a major role in deciding whether you are ready. If your recent AAMC exams consistently place you near the score you would be comfortable applying with, taking the September exam may be reasonable. If you are repeatedly far below your target and hoping for a dramatic test-day jump, the current application cycle is probably not a good reason to gamble with an MCAT attempt.

I would rather see you take the MCAT when you are prepared, earn the strongest score you reasonably can, and apply early the following cycle than take an exam you know you are not ready for and potentially enter the next application cycle with a score you now need to overcome.

Is a September MCAT Better for DO Schools?

A September MCAT may be more workable for some osteopathic medical schools because AACOMAS and individual DO programs can operate on timelines that extend later than many MD admissions cycles.

That does not mean every DO school treats an October score as early or that timing no longer matters. Programs establish their own deadlines and admissions procedures, so you should verify that each school accepts your September test date and determine when the application would become complete.

SDN discussions reflect this difference as well. Some experienced contributors are noticeably less concerned about September MCAT timing for DO applicants than for MD-only applicants, particularly when the rest of the application is already complete.

I would still build a DO school list because you genuinely want to attend those programs and are interested in osteopathic medicine, not simply because September made the MD timeline uncomfortable.

What About TMDSAS and Texas Medical Schools?

Applicants using TMDSAS need to evaluate the Texas timeline separately rather than applying AMCAS assumptions to every Texas school.

A recent SDN discussion about a September MCAT for the Texas cycle involved an applicant who had already received secondaries and planned to complete them before the new MCAT arrived. Even with that preparation, an experienced SDN contributor described the September-MCAT strategy as poorly aligned with maximizing success in that cycle because of how late the score would become available relative to the application timeline.

If you are applying through TMDSAS, I would check the current TMDSAS requirements and every school’s MCAT deadline directly. A school accepting a particular September test date only tells you that your application remains eligible; it does not tell you whether waiting for that score is competitively ideal.

What If You Already Submitted AMCAS Without Your MCAT Score?

If your primary has already been submitted, you have at least avoided waiting until October to begin AMCAS processing. Your application can move through verification while you prepare for the MCAT, and your official score can later become available through AMCAS after release.

This was similar to the approach I used in my own cycle, although I tested much earlier. I submitted AMCAS before receiving my MCAT score because my primary was otherwise ready, which allowed the administrative parts of the process to continue while I waited for the score.

For a September tester, I would use the waiting period aggressively but intelligently. Finish secondary essays where it makes financial and strategic sense, verify that letters have been received, check every school for additional assessment requirements, research your school list, and use a tracker so an administrative item does not create yet another delay after your score arrives.

My free AMCAS application checklist and medical school cost calculator is designed around exactly these separate stages because “submitted,” “verified,” “delivered,” and “complete” do not mean the same thing.

Should You Apply Before Knowing Your September MCAT Score?

I would base this decision largely on how predictable your likely score is and how much money you are willing to risk.

If your recent official AAMC full-length exams consistently fall within a narrow range that would make your current school list reasonable, submitting the primary and preparing secondaries before the score arrives may be easier to justify.

If your practice scores are highly variable or substantially below the level you need, applying broadly before October can become expensive. You may pay AMCAS designation fees and secondary fees at schools that no longer make sense once you see the actual result.

Your MCAT also affects how you construct the school list itself. Applying without the score is much easier when you have a realistic practice range than when you are effectively guessing whether you will finish with a 500, 507, or 515.

When I Would Still Consider a September MCAT for This Cycle

I would be most comfortable proceeding when your primary is already submitted and ideally verified, your secondary essays are completed or largely prewritten, your letters and other requirements are ready, your recent AAMC practice scores support the score you need, and you have confirmed that the schools on your list will accept the September test date.

I would also want your school list to be realistic enough that the late timing is not being combined with several other disadvantages. An applicant applying late with academic metrics substantially below a school’s range and weak mission fit is asking the application to overcome several problems simultaneously.

A September MCAT becomes more defensible when timing is the main weakness rather than one of many weaknesses.

When I Would Wait and Apply Next Cycle Instead

I would seriously consider waiting if you have not yet submitted your primary, your MCAT practice scores are not where they need to be, your application still needs substantial work, or you would be relying on an unexpectedly high September score to make your school list viable.

Waiting can be particularly valuable when the additional months would allow you to improve more than just the MCAT. You may be able to add meaningful clinical experience, deepen a service commitment, continue research, strengthen your writing, save money for application expenses, and enter the next cycle with your entire application prepared.

I came into the premed process without physicians in my family who could explain every part of this timeline to me, and I understand why adding another year can initially feel like losing time. Having gone through the application process and medical school since then, I would place much more value on applying once with the strongest application you can reasonably build than on protecting a particular matriculation year at all costs.

A September test can preserve the possibility of applying during the current cycle, but preserving the possibility is not always the same as maximizing your chance of acceptance.

My September MCAT Decision Checklist

Before taking the MCAT in September for the current application cycle, I would answer all of these questions:

1. Is my AMCAS or AACOMAS primary already submitted?
2. Has my primary already been verified?
3. Have I received or prewritten my secondary applications?
4. What exact date will my September MCAT score be released?
5. Does every school on my list accept that September MCAT date?
6. Will each school hold my application for the new score?
7. Do I already have an MCAT score schools could use before the retake arrives?
8. Are my recent AAMC full-length scores close to my target?
9. Would I still take this test in September if I were applying next cycle instead?
10. Am I taking the exam because I am ready or because I am afraid of delaying medical school?
11. Is my school list realistic for the score range I am currently producing?
12. Would applying early next cycle materially improve my odds compared with becoming complete in October?

If several of those answers create additional uncertainty, I would think carefully before allowing the current cycle to dictate your test date.

Is September Too Late to Take the MCAT for This Cycle? My Bottom Line

For most applicants targeting MD medical schools, September is very late to take the MCAT for the same application cycle because a September exam produces an October score. In 2026, the final September MCAT dates release scores on October 6 or October 13, which can leave an applicant becoming complete at schools months after applications first began entering review.

A September MCAT can still be workable in selected situations, especially when your primary application is already verified, your secondaries are completed, the schools on your list accept the test date, and your practice scores show that you are genuinely ready for the exam. Applicants targeting appropriate DO programs may also have more flexibility at some schools, although individual policies still need to be checked.

I would not take an MCAT you are unprepared for simply to preserve the current cycle. The MCAT score will become part of your application record, while the opportunity to apply early comes around again next year.

When I applied, I took my MCAT in early May and submitted AMCAS before the score was released, which allowed the application process to continue while I waited. Going through AMCAS, secondaries, interviews, and eventually receiving multiple medical school acceptances made me appreciate how much easier the process becomes when you avoid stacking one delay on top of another.

If September is your earliest realistic opportunity to earn a strong MCAT score and everything else is already complete, I would evaluate your schools individually before abandoning the cycle. If September is forcing you to rush the MCAT and the rest of your application is still unfinished, waiting and applying early next cycle will usually give you a much stronger position.

Frequently Asked Questions

Is September too late to take the MCAT for medical school?

September is very late if you plan to use the score during the same MD application cycle because the score will generally not be released until October. It may still be usable at schools that accept September testing, particularly when the rest of your application is already complete.

Can I take the MCAT in September and still apply this cycle?

Yes, but whether it is a good strategy depends on your application service, schools, existing MCAT scores, and how much of the application is already complete. You should confirm that each medical school accepts your specific September test date.

When will a September 2026 MCAT score come out?

For U.S. testing centers, September 3 and September 4, 2026 scores are scheduled for release on October 6. September 11 and September 12 scores are scheduled for October 13.

Is the September MCAT too late for MD schools?

For many MD applicants, it creates a significant timing disadvantage because schools waiting for the score may not consider the application complete until October. Individual medical schools have different MCAT deadlines and review policies, so the answer is not identical everywhere.

Is September too late for a DO application?

A September MCAT may remain viable at some DO schools because many osteopathic programs operate later into the cycle. You should still verify the school’s latest accepted MCAT date and consider when your complete application will actually enter review.

Can I submit AMCAS before my September MCAT?

Yes. AMCAS does not require an available MCAT score to begin processing and verifying your primary application. Submitting before score release can prevent you from adding AMCAS verification time after the October score release.

Will schools wait for my September MCAT score?

Some will, but you should not assume every school automatically holds an application for a future MCAT. Review each school’s policy or contact the admissions office if the pending score is critical to your application.

Should I submit secondaries while waiting for my September MCAT?

Submitting appropriate secondaries before the score arrives can reduce additional delays, particularly if the school will hold your application for the pending score. However, you should consider the financial risk of paying secondary fees when you do not yet know whether your MCAT result will make that school realistic.

Is a September MCAT retake too late?

A September retake can still be considered by some medical schools, but the new score may not arrive until October. Schools may already have access to your previous score, so you should determine whether each program will wait for the retake before reviewing your application.

Should I take a September MCAT or wait until January?

If you are not academically ready in September, I would rather see you take the exam later and apply strongly in the next cycle than rush into a September attempt solely to preserve the current application year. Your recent official AAMC full-length scores should be a major factor in that decision.

What is the latest MCAT date for the 2026 testing year?

For U.S. testing centers, the final scheduled 2026 MCAT date is September 12. Its scheduled score release date is October 13.

Is October too late for medical schools to receive my MCAT?

October is late for many rolling MD admissions processes, although it does not make admission universally impossible. Whether the application remains worthwhile depends on the individual medical school’s policies, your overall competitiveness, and whether everything else is already complete when the score arrives.
