The highest MCAT score is 528, and the AAMC's own percentile table puts at most about 510 examinees a year anywhere above 525, out of roughly 101,800 who sit the exam. Reaching it takes a 132 in all four sections at a single sitting, because 132 is the maximum section score and the total is just the four added together.
Those four ceilings are not equally hard to reach, which is the part no ranking page works out. The 100th percentile rank also starts three points below the top of the scale.
- 528 is the highest possible total score and 472 is the lowest. Both fall out of the 118 to 132 section scale.
- 132 is the maximum score on any one section, and a 528 means a 132 in all four at one sitting. There is no other route to it.
- At most about 510 examinees a year score anywhere above 525, out of roughly 101,800 who test.
- The four 132s are not equally scarce. Between 2.5 and 3.5 percent of examinees reach a 132 in Psych/Soc, against at most 1.5 percent in CARS.
- The 100th percentile rank starts at 525, not 528, so a perfect score and a 100th-percentile score are not the same thing.
- The 2025 to 2026 MD matriculant mean was 512.1, almost 16 points below the ceiling.
What is the highest MCAT score?
528, and the arithmetic behind it is simple. The AAMC scores each of the four sections from a low of 118 to a high of 132, with a midpoint of 125. Your total score is those four section scores added together.
So the ceiling of the total scale is 4 x 132 = 528, and the floor is 4 x 118 = 472. That gives 57 possible total scores. The total has no scale of its own to learn: if you know your four section scores, you already know your total. The AAMC's own worked example adds a 128, a 125, a 129 and a 127 to reach 509.
This also means a 528 is four ceilings at once, not one. You cannot offset a 130 in Chem/Phys with a 134 somewhere else, because 134 does not exist. Every section has to land on its own maximum on the same day.
If you're converting a practice test instead of a real score report, the MCAT score calculator turns raw correct answers into scaled section scores and a total. For the full picture of what every score on the scale is worth, we cover that separately in our guide to the MCAT score range, and the four sections themselves are broken down in their own guide.
How rare is a 528?
Rarer than the ranking pages suggest, and the AAMC's own table tells you roughly how much rarer.
The current percentile ranks are in effect from May 1, 2026 through April 30, 2027, and they're rebuilt every May 1 from the three most recent testing years. The table itself is built on 305,494 scores from the 2023, 2024 and 2025 testing years. Divide that by three and you get about 101,800 examinees a year.
Percentile rank here means the percentage of scores equal to or lower than yours. Here is the top of that table:
| Total score | Percentile rank | Share scoring this or higher |
|---|---|---|
| 515 | 91 | 11% |
| 520 | 97 | 4% |
| 521 | 98 | 3% |
| 522 | 99 | 2% |
| 523 | 99 | 1% |
| 524 | 99 | 1% |
| 525 | 100 | 1% |
| 526 | 100 | under 0.5% |
| 527 | 100 | under 0.5% |
| 528 | 100 | under 0.5% |
Share of examinees at or above each total score. Counts apply each share to the 305,494 scores AAMC reports across three testing years.
The AAMC prints percentile ranks as whole numbers, and that rounding is what lets you put a ceiling on the count. A printed 100 at a score of 525 means the true percentage of scores at or below 525 is at least 99.5. So everything above 525 is at most 0.5 percent of the sample. Half a percent of 305,494 is 1,527 scores across three years, or 509 a year.
At most about 510 examinees a year score 526, 527 or 528 combined, out of roughly 101,800 who test. A 528 on its own is a slice of that, so the real number of perfect scores is smaller still.
Run the same logic one point lower and you get a floor as well as a ceiling. A printed 99 at 524 means the true figure there is under 99.5, so more than 0.5 percent score 525 or higher, and at most 1.5 percent do. That puts somewhere between roughly 510 and 1,530 examinees a year at 525 or above.
Those bounds are wider than a single tidy statistic, and that's the honest shape of the data. Any page quoting an exact number of 528s a year is quoting something the AAMC does not publish.
That includes the answer box at the top of this search. Google's AI Overview for this query currently says that 30 to 70 test takers a year earn a perfect score, out of "roughly 200,000 to 300,000 students who take the exam each year", and it cites the AAMC percentile file as a source. That file reports 305,494 scores across three testing years, which is about 101,800 a year, so the volume figure is two to three times too high. The headcount is not in the file at all.
What is the maximum MCAT score for one section?
132, on every section, and this is where the four ceilings stop looking alike.
The same AAMC file carries a percentile table for each section. A 132 is the 100th percentile everywhere, but the rank printed one point below it is not the same from section to section, and that gap is what tells you how crowded each ceiling is.
| Section | Mean score | Percentile at 131 | Share scoring 132 | Examinees a year |
|---|---|---|---|---|
| Chemical and Physical Foundations | 124.9 | 99 | 0.5 to 1.5% | about 510 to 1,530 |
| Critical Analysis and Reasoning Skills | 124.6 | 99 | 0.5 to 1.5% | about 510 to 1,530 |
| Biological and Biochemical Foundations | 125.1 | 98 | 1.5 to 2.5% | about 1,530 to 2,550 |
| Psychological, Social and Biological Foundations | 125.9 | 97 | 2.5 to 3.5% | about 2,550 to 3,560 |
The reasoning is the same rounding argument as above, run on each section. A printed 97 at 131 in Psych/Soc means between 2.5 and 3.5 percent of examinees scored 132 there. A printed 99 at 131 in CARS means at most 1.5 percent did.
So a Psych/Soc 132 is roughly two to three times as common as a Chem/Phys or CARS 132. A 528 is not four equally hard ceilings. It is two scarce ones, one in between, and one that a few thousand people a year reach.
That matters for how you read a 131. In Psych/Soc a 131 leaves a visible group still above you. In CARS it does not. It also explains why the single-section maximum shows up far more often than the total maximum: thousands of people touch 132 somewhere each year, and almost nobody touches it in all four sections on the same morning. If one section is the one holding you back, our CARS tips deal with the hardest of the four.
Why the 100th percentile does not start at 528
Because the top of the scale is compressed, and the percentile table stops moving before the score does.
| Total score | Percentile rank |
|---|---|
| 519 | 96 |
| 520 | 97 |
| 521 | 98 |
| 522 | 99 |
| 523 | 99 |
| 524 | 99 |
| 525 | 100 |
| 526 | 100 |
| 527 | 100 |
| 528 | 100 |
The 100th percentile rank begins at 525, three full points below the maximum. Seven of the 57 possible total scores, everything from 522 up, share just two printed percentile ranks. Once you're at 525, the scale has nothing left to give you in percentile terms.
Worth checking your source on this one. Princeton Review's percentile table is headed "MCAT Percentiles 2023-2024", buckets the top as "524 to 528 = 100" and puts 515 at the 90th percentile. Blueprint's table does the same, and its own footnote dates it to the 2020, 2021 and 2022 testing years. The AAMC table in force since May 1, 2026 puts 524 at the 99th percentile and 515 at the 91st. Both of those pages move the 100th-percentile floor a point lower than the current data supports.
It's a small difference, and it matters mostly because of what it hides: the plateau at the top is real, and it starts earlier than a bucketed table lets you see.
Why 528 is the wrong target for almost every applicant
Look at what eight points are worth in two different places on the scale.
The same eight-point move is worth 26 percentile points in the middle of the scale and 3 at the top.
Going from 500 to 508 takes you from the 48th percentile to the 74th. That's 26 percentile points for eight scale points. Going from 520 to 528 takes you from the 97th to the 100th: three percentile points, for the same eight scale points, against the hardest questions the exam has.
The same collapse happens point by point, not just in eight point jumps: one scaled point is worth 3.2 percentile places between 500 and 505 but only 1.2 between 515 and 520.
Those eight points are also not equally hard to earn. The first eight come from fixing content gaps and timing. The last eight come from being near perfect in four separate sections on the same morning, with no room anywhere for a misread stem or a slow passage.
What actually gets people in
The admissions data sets the ceiling in context better than any percentile does. Students who matriculated to US MD programs in the 2025 to 2026 cycle averaged 512.1 on the MCAT, across 23,440 matriculants. That is the 84th percentile, and it sits 15.9 points below 528.
The section averages say the same thing. No matriculant section mean reaches 129: Psych/Soc is highest at 129.0, then Bio/Biochem at 128.2, Chem/Phys at 128.0 and CARS at 127.0. The average admitted student is three to five points short of the ceiling in every single section, and still admitted.
That average has also barely moved. It was 511.5 for the 2020 to 2021 entering class and 512.1 for 2025 to 2026, a rise of 0.6 points across six cycles. The bar for admission is close to flat while the top of the scale never moves at all.
None of which makes a high score worthless. It means the return on each additional point collapses well before 528, and the effort you'd spend chasing the last three points almost always does more for you somewhere else in the application. If you're deciding whether your current score is already enough, our breakdown of whether a 508 is a good MCAT score walks through how to read your own number, and the MCAT statistics dashboard has the applicant and matriculant averages by year.
If you're sitting on a score you're unhappy with, the useful question isn't how close you can get to 528. It's whether a retake moves you enough to change outcomes, which the retake calculator is built to answer. And if you're still at the start, our honest read on how hard the MCAT is sets a more useful expectation than the top of the scale does. Before you pick any target, sit a free MCAT diagnostic and find out which end of that curve you are actually starting from. Everything else we publish for this exam sits on the MCAT hub.
Highest MCAT score FAQs
Has anyone ever gotten a 528 on the MCAT?
Yes. A 528 is an attainable score, and the AAMC reports a percentile rank for every total score up to and including 528. What the AAMC does not publish is a headcount, so treat any specific "N people got a 528 last year" figure with suspicion. The tightest honest statement the published table supports is that at most about 510 examinees a year score anywhere above 525, and 528 is a fraction of that group.
Has anyone ever gotten 100% on the MCAT?
The MCAT does not report a percentage, so there is no 100% to get. Scoring is scaled and equated across test forms, which means you can miss questions and still earn a 132 in a section, and the number of questions you can miss changes from one form to the next. The closest thing to a perfect result is a 528, which is a 132 in all four sections. A 100th percentile rank is a different thing again: it starts at 525.
What is the highest MCAT section score?
132, on each of the four sections, with 118 as the floor and 125 as the midpoint. A 132 is the 100th percentile in every section, but it is not equally rare in each: between 2.5 and 3.5 percent of examinees reach it in Psychological, Social and Biological Foundations, against at most 1.5 percent in CARS and in Chemical and Physical Foundations.
How rare is a 520 MCAT score?
A 520 is the 97th percentile, which means about 4 percent of examinees score 520 or higher. Across roughly 101,800 test takers a year, that's somewhere near 4,100 people. It is a genuinely excellent score, and it sits only three percentile points below a perfect 528.
Do you need a 528 to get into medical school?
No. No school requires a perfect score, and both the percentile table and the admissions data show why the idea doesn't hold up. A 520 already beats 96 percent of everyone who takes the exam, the last eight points on the scale are worth only three percentile points, and the average student admitted to a US MD program in the 2025 to 2026 cycle scored 512.1. Look up the score ranges your target schools actually report and aim at those rather than at the ceiling.
