About the MCAT Score Calculator
This MCAT score calculator estimates your scaled scores from a practice exam. Enter the number of questions you answered correctly in each section — Chemical and Physical Foundations (59 questions), Critical Analysis and Reasoning Skills (CARS, 53), Biological and Biochemical Foundations (59) and Psychological, Social and Biological Foundations of Behavior (59) — and it converts each to the 118–132 scale, adds them into a 472–528 total and shows the AAMC percentile rank for every score.
It suits pre-med students tracking practice tests, planning which section to study next, or judging whether they are ready for test day. The percentile ranks are the AAMC figures in effect from May 1, 2026 to April 30, 2027, based on everyone who tested in 2023, 2024 and 2025.
AAMC equates every test form, so the exact raw-to-scaled conversion differs slightly from form to form. This calculator uses a representative curve consistent with AAMC’s own example — 35 to 37 correct is about a 123 and 46 to 48 correct is about a 128 — so treat each section score as an estimate that can differ from your official score.
With the default inputs, the estimated total score is 510. Change any value above to recalculate instantly.
How to use the mcat score calculator
- 1Take a full-length practice MCAT under timed conditions.
- 2Count the questions you got right in each of the four sections.
- 3Enter the four raw scores.
- 4Read your estimated section scores, total and percentile ranks.
- 5Use the table to find your weakest section and focus your next study block there.
Formula and method
Each MCAT section is scored from the number of questions answered correctly; wrong answers count the same as blanks. AAMC converts the number correct to a 118–132 scaled score through equating, which adjusts for small differences in difficulty between forms, so there is no curve against other test takers.
This calculator maps your number correct onto a representative conversion for a 59-question section (scaling CARS from 53 questions), consistent with AAMC’s illustration that 35–37 correct is about 123 and 46–48 correct about 128. The total is the sum of the four section scores. Percentiles are the AAMC ranks in effect May 2026–April 2027: the percentage of scores equal to or below yours.

Worked examples
Solid practice exam (45 / 40 / 46 / 48)
45/59 in Chem/Phys converts to about 127, 40/53 in CARS to 127, 46/59 in Bio/Biochem to 128 and 48/59 in Psych/Soc to 128. The total is 510, which the AAMC table places at the 79th percentile.
Around the midpoint
About two-thirds correct in each section gives scores near the 125 midpoint. The total of 501 is at the 52nd percentile, just above the 2023–2025 mean of 500.6.
High scorer
Missing only a handful of questions gives 131 in the three science sections and 130 in CARS (48 of 53). The 523 total is at the 99th percentile in the current AAMC table.
Frequently asked questions
How is the MCAT scored?+
Each of the four sections is scored from 118 to 132 with a midpoint of 125, and the total ranges from 472 to 528 with a midpoint of 500. Scores are based on the number of correct answers, with no penalty for wrong answers.
Is the MCAT curved?+
No. AAMC scales and equates each test form so a given score means the same thing whenever you test. Your score does not depend on how other people taking the exam on the same day performed.
What is a good MCAT score?+
A 500 is about the 48th percentile, 510 about the 79th and 515 about the 91st in the current AAMC table. Many MD programs report matriculant medians in the 510–520 range, so check the schools on your list.
How many questions are on each MCAT section?+
Chemical and Physical Foundations, Biological and Biochemical Foundations, and Psychological, Social and Biological Foundations each have 59 questions in 95 minutes. CARS has 53 questions in 90 minutes.
When are MCAT percentile ranks updated?+
AAMC updates percentile ranks every May 1 using the three most recent testing years. The ranks used here are in effect from May 1, 2026 to April 30, 2027 and are based on 2023–2025 examinees.
