How is the MCAT scored?
The MCAT is scored on a 472 to 528 scale. Each of the four sections is scored from 118 to 132, and those four section scores are added together to produce your total. The midpoint is 500. There is no passing score - the MCAT is not pass or fail, so results are reported alongside percentile ranks that show where your total stands.
The rest of this guide unpacks each piece: how the section scores are equated, how the total is built, what the percentile table actually says, why no passing score exists, and how release timing and retake limits shape your plan.
How is each MCAT section scored?
The MCAT has four scored sections, and each one is scored independently on a scale from 118 to 132, with 125 as the midpoint. The four sections are Chemical and Physical Foundations of Biological Systems (Chem/Phys), Critical Analysis and Reasoning Skills (CARS), Biological and Biochemical Foundations of Living Systems (Bio/Biochem), and Psychological, Social, and Biological Foundations of Behavior (Psych/Soc). Three of the four are science sections built from passage-based question sets plus discrete questions; CARS is entirely passage-based and contains no discrete questions. Every question is multiple choice, and there is no penalty for guessing, so you should answer all 230 questions.
The raw number of questions you answer correctly is converted to a scaled score, and that conversion is equated across test forms. Equating means a 128 in Chem/Phys represents the same level of achievement no matter which test date or form you sat, so you are never advantaged or disadvantaged by drawing a slightly harder or easier version of the exam. Because the score is scaled, you cannot work backward from a raw percentage; missing a few questions on a harder form can still land the same scaled score as a cleaner run on an easier form.

- •Four sections, each scored 118 to 132 with a midpoint of 125.
- •230 questions total; content time is 6 hours 15 minutes, and total seated time is about 7 hours 30 minutes once you add the tutorial, breaks, and optional survey.
- •No guessing penalty - answer every question, because a blank scores the same as a wrong answer.
How does the 472 to 528 total score work?
Your total MCAT score is simply the sum of your four section scores. Because each section ranges from 118 to 132, the total runs from 472 at the floor to 528 at the ceiling, with 500 as the midpoint. For example, section scores of 128, 125, 129, and 127 add up to a total of 509. There is no weighting - every section contributes equally, so a strong section can offset a weaker one point for point, but a single weak section still pulls the total down by exactly the points it loses.
Two totals that look identical can hide very different profiles. A 508 built from four balanced sections around 127 reads differently to admissions committees than a 508 with one section at 122 and another at 132, even though the number is the same. That is why your score report shows all four section scores, not just the total, and why the section breakdown matters when you plan a retake or decide whether a single weak area is worth a second sitting.
- •Total score = Chem/Phys + CARS + Bio/Biochem + Psych/Soc.
- •Range 472 to 528; midpoint 500; worked example 128 + 125 + 129 + 127 = 509.
- •No section is weighted more heavily than another - each point counts the same toward your total.
What do MCAT percentiles mean?
A percentile rank tells you the share of test takers who scored at or below your total. Because the MCAT has no passing score, percentiles are how you judge where a result actually stands. The AAMC recalculates the percentile table every year on May 1, using the most recent three years of testers. The table in effect from May 1, 2026 through April 30, 2027 is based on 2023 to 2025 examinees - a group of 305,494 test takers with a mean total of 500.6 and a standard deviation of 11.2.
The midpoint is not the median you might assume. A total of 500 sits at roughly the 48th percentile, and because the scale is tight, small point gains move you a lot near the middle: 500 is about the 48th percentile, 505 is about the 64th, and 510 is about the 79th. At the top, the curve flattens - 520 already reaches the 97th percentile, and everything from 525 up rounds to the 100th. The table below lists the anchor points on the current scale.
Section percentiles do not line up with the total. The section midpoint of 125 is not the 50th percentile in every section: on the current table it falls near the 56th percentile in Chem/Phys, the 62nd in CARS, the 53rd in Bio/Biochem, and the 44th in Psych/Soc, reflecting section means of 124.6, 125.1, 124.9, and 125.9 respectively. So the same scaled score carries a slightly different percentile depending on which section it came from.

| 528 | 100 |
| 522 | 99 |
| 520 | 97 |
| 518 | 95 |

Is there a passing MCAT score?
No. The MCAT is not a pass or fail exam, and the AAMC does not set a passing score. There is no line that separates a pass from a fail, which is why you should ignore any source that quotes an MCAT pass rate - none exists. Instead, each medical school sets its own expectations, and those expectations are usually expressed as an average or a competitive range for admitted students rather than a hard cutoff. Some schools also weigh the AAMC PREview professional readiness exam alongside the MCAT.
In practice, what counts as a strong score depends entirely on where you are applying. Many US MD programs admit classes with median totals in the low 510s, while some programs sit lower and the most selective schools sit higher. Because the target is school-specific, the useful question is not whether you passed but whether your total and section scores clear the range your target schools actually admit. Our guide on what a good MCAT score looks like breaks the ranges down by program type so you can set a realistic target.
When do MCAT scores come out, and how many times can you retake?
Official MCAT scores are released 30 to 35 days after your test date - considerably slower than most admissions tests, so build that wait into your application timeline. Your score report shows all four section scores, your total, the percentile rank for each, and confidence bands that indicate the range your true performance likely falls within. Scores are released through your AAMC account, and there is no separate rush option, so the release window is effectively fixed once you have tested.
Retakes are capped. You can sit the MCAT up to three times in a single testing year, four times across two consecutive years, and seven times over your lifetime. No-shows and voided exams count against those limits, so do not register for a date you are unsure about. Score validity is set by each medical school rather than the AAMC: the AAMC keeps your scores available for several years, and most schools accept results that are two to three years old, but you must confirm the accepted window with every program you apply to.
30 to 35 days after test day
Scores post to your AAMC account - all four section scores, the total, the percentile rank for each, and confidence bands. There is no rush option.
Retake limits
Up to 3 times per testing year, 4 across two consecutive years, and 7 in a lifetime. No-shows and voided exams count toward every limit.
Score validity
Set by each school, not the AAMC. Most programs accept scores 2 to 3 years old, but confirm the exact window with each recipient.
What if your MCAT score is lower than you need?
A disappointing score is rarely the end of the road, but a retake is a real commitment of time and money, so diagnose before you rebook. Look at the section breakdown: a single section trailing the others by several points is a targeted-prep problem you can often close, while a total that is uniformly low usually means the content foundation needs more time than a quick second attempt allows. Weigh the retake limits too - you only get so many sittings, and every one counts, including no-shows and voids. Planning a realistic study runway from the start beats scrambling for a retake later.
When the gap is real and a deadline is close, Exam Assist supports MCAT candidates on pay-after-pass terms: you pay only after you reach your target score, not upfront for hours of tutoring. Message us with your test date, the total and section scores you need, and where you are strongest and weakest, and we will lay out your options confidentially. Exam Assist is independent and is not affiliated with the AAMC or the MCAT program.
Whichever route you take, aim the next attempt at the specific points you are missing rather than restudying everything evenly - the section scores tell you exactly where the ground is. And if your path runs beyond admissions into medical licensing and nursing, the same confidential support extends to related exams such as the USMLE and the DAT, and our study references cover the MCCQE Part 1 and the NCLEX-RN too.
