Use the MCAT score calculator below by entering how many questions you answered correctly in each section of a practice exam. The calculator shows estimated section scores and percentiles, an estimated total score and its MCAT percentile rank. You can also use it as an MCAT score converter for practice exams that report only the number correct, including the free AAMC Unscored Sample Test.
Your result is an estimate rather than an official MCAT score, so use it to compare sections and track your practice exams over time, not to predict an admissions decision.
MCAT Score Calculator at a Glance
- Enter the number of correct answers separately for Chem/Phys, CARS, Bio/Biochem and Psych/Soc.
- Treat the section scores, total score and percentile ranks as estimates because raw-to-scaled conversions can vary between exam forms.
- The calculator works as a score converter for the free AAMC Unscored Sample Test, which does not provide scaled scores or percentile ranks.
- The conversion table below lists the number correct behind each estimated section score from 118 to 132, so you can check any result by hand.
AAMC Unscored Sample Test Score Converter
The free AAMC Unscored Sample Test does not give you a scaled score or a percentile rank. To convert your result, find the number of questions you answered correctly in each section on your Sample Test score report and enter each section’s number correct in the calculator above. According to the AAMC exam overview, Chem/Phys, Bio/Biochem and Psych/Soc each have 59 questions and CARS has 53, so check every entry against the right section total.
The table below shows the same conversion the calculator uses: the range of correct answers behind each estimated scaled section score from 118 to 132. Add your four section scores to get an estimated total. These are International Medical Aid’s estimate ranges, not an official AAMC conversion. The number correct needed for a given score varies from one exam form to the next, so your official result may differ.
| Estimated scaled section score | Chem/Phys number correct (of 59) | CARS number correct (of 53) | Bio/Biochem number correct (of 59) | Psych/Soc number correct (of 59) |
|---|---|---|---|---|
| 132 | 58 to 59 | 51 to 53 | 57 to 59 | 57 to 59 |
| 131 | 56 to 57 | 49 to 50 | 55 to 56 | 55 to 56 |
| 130 | 53 to 55 | 47 to 48 | 52 to 54 | 52 to 54 |
| 129 | 50 to 52 | 46 | 50 to 51 | 50 to 51 |
| 128 | 47 to 49 | 43 to 45 | 47 to 49 | 47 to 49 |
| 127 | 43 to 46 | 41 to 42 | 44 to 46 | 44 to 46 |
| 126 | 39 to 42 | 39 to 40 | 41 to 43 | 41 to 43 |
| 125 | 36 to 38 | 36 to 38 | 38 to 40 | 38 to 40 |
| 124 | 31 to 35 | 33 to 35 | 35 to 37 | 35 to 37 |
| 123 | 28 to 30 | 30 to 32 | 31 to 34 | 31 to 34 |
| 122 | 24 to 27 | 27 to 29 | 28 to 30 | 28 to 30 |
| 121 | 21 to 23 | 24 to 26 | 24 to 27 | 24 to 27 |
| 120 | 18 to 20 | 20 to 23 | 20 to 23 | 20 to 23 |
| 119 | 16 to 17 | 16 to 19 | 17 to 19 | 17 to 19 |
| 118 | 0 to 15 | 0 to 15 | 0 to 16 | 0 to 16 |
How to Use the MCAT Score Calculator
Start with the score report from your practice exam. Enter the number of questions you answered correctly for Chem/Phys, CARS, Bio/Biochem and Psych/Soc in their own rows so the calculator applies the right range to each one. Use the number correct, not a percentage, a scaled score or the number missed.
IMA’s calculator displays an estimated scaled score and percentile for each section. It then combines the four section scores and shows an estimated total score, its percentile rank and the share of test takers who scored at or below that result on a score bar running from 472 to 528. Use the reset button before entering another practice exam.
How Is the MCAT Scored?
The MCAT is scored out of 528. Each of the four sections receives a scaled score from 118 to 132, and the four section scores add up to a total from 472 to 528. Every section score starts from the number of questions you answer correctly.
The AAMC scoring process has three main steps. First, the number of correct answers is counted separately for each section. Second, each number correct is converted to a scaled section score. Third, the four scaled scores are added to produce your total.
There is no penalty for an incorrect or unanswered question, so the AAMC advises answering every question. For an illustration of conversion, the AAMC says 35 to 37 correct answers might become a section score of 123, while 46 to 48 correct answers might become 128. These are examples, not fixed thresholds that apply to every form, which is also why they do not line up exactly with the estimate ranges in IMA’s table.
According to the AAMC, each section has a midpoint of 125 and the total scale has a midpoint of 500. Official score reports show scaled scores, not raw scores.
Scaling and equating make scores from different exam forms comparable, so two students of equal ability taking different forms would be expected to receive the same scaled score. That is not a curve. The AAMC explanation of MCAT scoring states that the exam is not curved and that scaled scores keep the same meaning regardless of the test date.
Official scores take 30 to 35 days to become available. During that period, each form is scaled and equated, and concerns submitted by test takers are reviewed.
Which Practice Exams Should You Enter?
The calculator is most helpful when a practice exam reports how many questions you answered correctly but does not supply scaled scores. The AAMC offers two free full-length practice exams and five low-cost exams. IMA’s MCAT practice test guide explains how these resources differ.
Practice Exam 1 is free, contains 230 questions from previously administered MCAT exams and already provides a scaled score and percentile rank. Practice Exams 2 through 6 do the same, and each costs $35 for one year of access, as listed by the AAMC on September 14, 2026.
The free Unscored Sample Test also contains 230 questions and has the same look, length and functionality as the actual exam. It is the AAMC full-length exam that needs a converter, as described near the top of this page.
If an AAMC practice exam already gives you a scaled result, use that result rather than the calculator’s estimate. Each MCAT section also contains field-test questions that are being considered for future use and do not count toward the official score.
Reading Your Estimated Percentile
A percentile rank is the percentage of test takers who earned the same score or a lower score. For complete score tables and interpretation, see IMA’s MCAT percentiles guide linked at the top of this page.
The AAMC updates percentile ranks every May 1 using scores from the most recent three years. The ranks in effect from May 1, 2026 through April 30, 2027 use results from everyone who tested in 2023, 2024 and 2025, a population of 305,494 results. In that table, 500 corresponds to the 48th percentile, 505 to the 64th, 510 to the 79th, 515 to the 91st and 520 to the 97th.
The calculator uses these same AAMC ranks, so note the period whenever you record a percentile. Official score reports also include confidence bands that communicate the accuracy of section and total scores.
What Does Your MCAT Estimate Mean for Medical School?
An estimated MCAT score cannot tell you whether you are a competitive applicant. The AAMC says there is no single score that makes someone competitive because admissions officers consider MCAT results together with experiences, attributes, demographics and transcripts. Students are accepted with a wide range of scores, and high MCAT scores and GPAs do not guarantee admission. IMA’s guide to what MCAT score you need for medical school covers that context.
For the 2025-2026 academic year, applicants to U.S. MD-granting medical schools had a mean total MCAT score of 506.3 and matriculants had a mean of 512.1. These are group averages rather than minimum requirements. IMA’s explanation of what counts as a good MCAT score shows how to read your result against them.
Using the Calculator in Your Study Plan
The AAMC suggests starting with the free Unscored Sample Test to establish a baseline, then using its Content and Skills Breakdown to identify knowledge gaps. Convert that result with the calculator and record the four estimated section scores.
Next, the AAMC suggests taking Practice Exam 1 under test-day timing conditions so you become familiar with the exam’s functionality. IMA’s guide to how long the MCAT is lists the section timing and breaks to follow. Because that exam supplies its own scaled score, you can compare it with your estimated baseline.
After each practice exam, review every incorrect or flagged question, identify why you missed it and decide how you will address the issue. The AAMC advises spending substantial time on your weaknesses between full-length exams. IMA’s guide on how to study for the MCAT can help you organize that work. When you enter a later result, compare its section scores with your earlier entries, because section movement tells you more than the total does.

Frequently Asked Questions
How Accurate Is an MCAT Score Calculator?
An MCAT score calculator provides an estimate, not an exact or official score. IMA’s tool uses practice exam score ranges, while each official MCAT form is scaled and equated after test day, so your official result may differ.
How Do You Convert MCAT Raw Scores to Scaled Scores?
You convert a practice raw score by entering the number of correct answers for each section in the calculator or by finding that number in the conversion table on this page. Each section converts to an estimated scaled score from 118 to 132, and the four estimates add to a total from 472 to 528. The conversion is approximate because official conversions are not constant across forms.
What Is the MCAT Out Of?
The MCAT is scored out of 528, the highest possible total score. Each of its four sections is scored from 118 to 132, which makes 472 the lowest possible total. Enter your number correct for each section in the calculator to see where a practice result falls on that scale.
How Many Questions Are in Each MCAT Section?
Chem/Phys, Bio/Biochem and Psych/Soc each contain 59 questions. CARS contains 53 questions. Enter your number correct against the matching section total.
Is the MCAT Graded on a Curve?
No, the MCAT is not graded on a curve. The exam is scaled and equated so scores are intended to have the same meaning across different forms and test dates. Your score therefore does not depend on the performance of people testing on the same day.
How Do I Convert My AAMC Unscored Sample Test Score?
Find the number of questions you answered correctly in each section of the AAMC Unscored Sample Test, then enter those four numbers in the calculator or look them up in the converter table on this page. The Sample Test does not supply scaled scores or percentile ranks, so the result is an IMA estimate for each section, not an official AAMC score.
Is There a Penalty for Wrong Answers on the MCAT?
No, the MCAT does not subtract points for wrong or unanswered questions. The AAMC advises answering every question because each section score begins with the number answered correctly.
What Percentile Is a 510 on the MCAT?
A total MCAT score of 510 has a percentile rank of 79 in the ranks effective from May 1, 2026 through April 30, 2027. That means 79 percent of the comparison population received the same score or a lower score.
