How Many Times Can You Take the MCAT? The Limits, and How Schools Read Attempts

There are two answers to “how many times can you take the MCAT.” One is the legal answer, meaning what the AAMC permits. The other is the practical answer, meaning what medical schools will tolerate before your attempt history starts working against you. Those two numbers are not the same, and treating the first as if it were the second is how students burn attempts they later wish they still had.

I scored a 527 and I run a tutoring company. We publish free MCAT books and a free question bank because I would rather compete on quality than on gatekeeping. So take this as a plain read of the rules, and confirm anything that touches your money or your timeline against the AAMC directly.

The limits, in one table

The AAMC caps MCAT attempts at three levels. Here is the whole policy in one place.

Window	Maximum attempts
One testing year	3
Two consecutive testing years	4
Lifetime	7

A few things about that table. A testing year is the AAMC’s exam calendar for a given year, which runs from January through September of scheduled test dates (see our 2026 MCAT test dates for the actual calendar). The lifetime count started with the April 2015 exams, so scores from the older paper era do not eat into your seven. And these caps stack: you could take the exam three times in one year, but that would leave you only one attempt in the following year to stay under the four-in-two-years rule.

One more point that surprises people. The lifetime limit is firm. There is no appeal process that hands you an eighth attempt, so the seven you have are all you will ever get. In practice almost nobody approaches that ceiling, because the schools you are applying to will have stopped you long before the AAMC does.

What actually counts as an attempt

This is where students lose attempts without meaning to. An attempt is not “a score you kept.” It is any registration that reaches test day and is not formally canceled in time.

That means the following all count against all three limits:

• A scored exam. Obviously.
• A voided exam. If you sit the full exam and then void your score at the end so no school ever sees it, you still spent one of your seven. Voiding protects your record, not your attempt count. If you are weighing that decision on test day, read should I void my MCAT first, because the right answer is usually no.
• A no-show. If you register and simply do not appear, you lose the attempt and the fee.

The only way to walk it back is to cancel your registration before the AAMC’s final deadline. Cancel in time and the attempt does not count, though you may forfeit part of the fee depending on how close to test day you are.

So the working definition is simple. Once you are inside the cancellation deadline, that registration is an attempt. Void, no-show, or score, the count goes up by one.

The number that matters is not the AAMC’s

Here is the part the “how many times can you take the MCAT” articles usually skip. The AAMC’s seven is a ceiling, not a target, and it is not the number that governs your application. Medical schools are.

Every MCAT attempt from your recent testing history is reported to AMCAS automatically. You cannot hide an attempt, you cannot send only your best score, and you cannot pick which ones a school sees. They all show up. Our full breakdown of that is in do med schools see all your MCAT scores, and the short version is this: assume every attempt is visible, because it is.

That changes the math. A first retake is normal and carries essentially no stigma. A second retake, meaning a third total attempt, starts to draw questions. By the time an admissions committee sees four or five attempts, the scores themselves matter less than the story they tell, which is a student who kept registering without changing the outcome. Adcoms read that as poor judgment about when to test, and judgment is exactly what they are screening for.

So the practical limit is not seven. For most applicants it is three total attempts, and ideally two. The AAMC will let you keep going. Your target schools quietly will not.

Budget your attempts like a scarce resource

If the real limit is two or three, then each attempt is expensive, and the fix is to stop treating your first sitting as a free trial. It is not. It is one of a very small number of shots, and it goes on your permanent record the moment you pass the cancellation deadline.

The single most useful rule I give students: do not schedule your first real attempt until your practice exams say you are ready. That means official AAMC full-lengths, taken under real conditions, landing in your target range consistently, not once. Your practice average is the best predictor you have of your real score, and the gap between the two is smaller than most students hope. We cover exactly what practice scores do and do not predict in practice test scores vs. actual.

The mistake is registering first and hoping the score catches up. If you test before you are ready, you do not get a clean redo. You get a low score on your record and one fewer attempt in the bank. Budgeting attempts means earning your test date with your practice scores, not with the calendar.

The retake decision is its own question

Everything above is about the rules and the budget. Whether you should actually spend one of your remaining attempts on a retake is a separate decision, and it deserves its own analysis. I wrote that up in full in should you retake the MCAT, which walks through the AAMC score-change data (most retakers gain only a couple of points, and nearly one in four score lower) and the questions to answer before you register again.

If you want a faster read on your specific situation, run the numbers through our MCAT retake calculator. It weighs your current score against your target schools and tells you whether a retake is likely to move the needle enough to be worth the attempt. Use both together: the calculator for a quick verdict, the retake guide for the how.

An attempt budget, worked two ways

Attempts are cheap to waste and hard to recover, so it helps to plan them against your actual timeline. Here are two common ones.

	Traditional applicant	Career changer
Situation	Junior year, applying next summer	Post-bacc, applying in two cycles
Attempts to plan for	1, with a retake held in reserve	1, with room for 1 retake
First test date	Spring of junior year, once AAMC full-lengths are in range	End of coursework, once practice scores stabilize
Retake window if needed	Summer, before the cycle closes	Following winter or spring, with a real study gap
Attempts kept in the bank	Well under the four-in-two-years cap	Comfortably under the same cap

The traditional applicant has one clean shot before applications and one safety attempt if test day goes sideways. The career changer has a longer runway and can afford a diagnosed, well-prepared retake without crowding the two-year window. Neither plan comes anywhere near seven, and that is the point. A good plan uses two attempts at most and treats the third as an emergency, not an expectation.

The bottom line

You can take the MCAT three times in a testing year, four times across two consecutive years, and seven times in a lifetime, and voids and no-shows count against every one of those numbers. But the AAMC’s ceiling is not your real constraint. Your schools see every attempt, and they stop finding extra attempts charming well before you reach seven. Plan for two, earn each test date with your practice scores, and let the retake calculator and the retake guide handle the one decision this post does not: whether to spend the next attempt at all.
