How to Use the MCAT Score & Percentile Calculator
The Medical College Admission Test (MCAT) developed and administered by the Association of American Medical Colleges (AAMC) is a standardized, multiple-choice examination required by nearly all US and Canadian medical schools. The test assesses problem-solving, critical thinking, and knowledge of natural, behavioral, and social science principles prerequisite to the study of medicine.
Formula and Calculation Methodology
- Section Scale: Each of the four sections is scored from 118 to 132, with a midpoint of 125
- Composite Scale: Sum of all four sections creates a total scaled score ranging from 472 to 528 (midpoint 500)
- Percentile Ranking: Benchmarked against historical AAMC applicant matriculant data
The examination consists of four distinct sections, each scored from 118 to 132: Chemical and Physical Foundations; Critical Analysis and Reasoning Skills (CARS); Biological and Biochemical Foundations; and Psychological, Social, and Biological Foundations. Total composite scores range from 472 to 528 with a nationwide midpoint centered at 500.5. Our calculator accurately converts section raw questions into scaled composite scores and national percentile brackets.

Frequently Asked Questions
What is considered a competitive MCAT score for US medical schools?
The average MCAT score for students matriculating into US MD schools is approximately 511 to 512. For DO (Doctor of Osteopathic Medicine) schools, the average matriculant score is around 504 to 506.
Why is CARS often considered the hardest MCAT section?
Unlike the science sections which test memorized biochemical pathways and physical formulas, CARS tests deep philosophical and literary textual analysis under severe time constraints, with fewer total questions (53 questions).
Is there a penalty for wrong answers on the MCAT?
No. There is no penalty for incorrect answers. Test-takers should never leave any question unanswered on test day.
