The Medical College Admission Test (MCAT) is scored on a scale specifically designed by the AAMC to give medical schools a standardized way to compare applicants. Understanding how the MCAT is scored is the first step toward setting a realistic target and building an effective study plan.
The Four MCAT Sections and Their Score Ranges
The MCAT consists of four sections, each scored on a scale of 118 to 132, with a midpoint of 125:
- Chemical and Physical Foundations of Biological Systems (Chem/Phys) — Tests general chemistry, organic chemistry, physics, and biochemistry in the context of biological systems.
- Critical Analysis and Reasoning Skills (CARS) — Assesses reading comprehension and analytical reasoning using passages from the humanities and social sciences. No outside science knowledge is required.
- Biological and Biochemical Foundations of Living Systems (Bio/Biochem) — Covers biology, biochemistry, and organic chemistry with an emphasis on how living systems function.
- Psychological, Social, and Biological Foundations of Behavior (Psych/Soc) — Tests psychology, sociology, and biology as they relate to health, disease, and human behavior.
Your four section scores are summed to produce a total score ranging from 472 to 528, with a midpoint of 500. Scores are scaled and equated across test dates to ensure fairness regardless of when you take the exam.
Key fact: A total score of 500 corresponds to roughly the 50th percentile, meaning you scored higher than half of all MCAT test takers. Each point above 500 moves you meaningfully higher in the percentile rankings.
MCAT Score Percentiles: What Your Score Really Means
Percentile rankings are arguably more important than raw scores because they tell you exactly where you stand relative to every other test taker. The AAMC updates percentile tables annually using a rolling three-year data set. Here is a general breakdown:
- 522–528: 99th+ percentile — Top 1% of all test takers
- 518–521: 98th–99th percentile — Exceptionally strong
- 514–517: 95th–98th percentile — Highly competitive
- 510–513: 88th–95th percentile — Competitive for most MD programs
- 506–509: 75th–88th percentile — Solid for many MD and DO programs
- 502–505: 55th–75th percentile — Competitive for DO and some MD programs
- 498–501: 35th–55th percentile — Below average for MD; competitive for DO
- 494–497: 20th–35th percentile — May benefit significantly from retaking
- 490–493: 10th–20th percentile — Consider a significant study overhaul
- 486–489: 5th–10th percentile
- 472–485: Below 5th percentile
What Is a Good MCAT Score?
A “good” MCAT score depends entirely on your target medical schools. Here is a practical framework:
- 520+ (98th+ percentile): Competitive for top-tier and Ivy League medical schools — Harvard, Johns Hopkins, UCSF, Stanford, Mayo Clinic.
- 515–519 (90th–97th percentile): Strong for highly competitive programs — UC San Diego, UCLA, University of Michigan, Georgetown, Emory.
- 508–514 (73rd–88th percentile): Competitive for most accredited MD programs and very strong for DO programs. This is the range where the majority of accepted MD applicants fall.
- 502–507 (55th–77th percentile): Competitive for osteopathic (DO) programs and lower-tier MD programs. Consider whether a retake with targeted preparation could move you into the 510+ range.
- Below 502 (below 55th percentile): A retake is generally recommended for MD applicants. A focused tutoring plan can make a dramatic difference.
The national average total MCAT score is approximately 500 (50th percentile). The average score for students who matriculate at allopathic (MD) medical schools is approximately 511–512.
How Private MCAT Tutoring Can Improve Your Score
Many students hit a plateau with self-study or large group courses because these approaches are not tailored to their specific weaknesses. Private MCAT tutoring changes that equation entirely.
Dr. Stuart Donnelly, an Oxford-trained Ph.D. with more than 20 years of full-time MCAT tutoring experience, specializes in helping students break through score plateaus. His approach includes:
- Score report analysis: Identifying exactly which content areas and question types are holding you back.
- Targeted content review: Focusing study time on your weakest areas rather than re-covering material you already know.
- CARS strategy development: Building systematic approaches to the passage-based reasoning that many students struggle with most.
- Practice test optimization: Learning how to analyze your practice exams for maximum improvement per hour of study.
- Test-day strategy: Pacing, stamina management, and techniques for handling the 7.5-hour exam day.
Students working with Dr. Donnelly typically improve their total MCAT score by 10–15 points, which can mean the difference between a 500 (50th percentile) and a 512 (88th percentile) — or between a 505 (70th percentile) and a 518 (98th percentile).

Frequently Asked Questions About MCAT Scores
The MCAT total score ranges from 472 to 528, with a midpoint of 500. Each of the four sections is scored on a scale of 118 to 132, with a midpoint of 125. The total score is the sum of all four section scores.
The average MCAT score for accepted MD students is approximately 511–512 (83rd–88th percentile). However, the score you need depends on your target schools. Top-tier programs like Harvard and Johns Hopkins average 520+, while competitive state schools typically look for 510–515. DO programs generally accept students with scores of 502–508.
The AAMC calculates percentile ranks using data from all MCAT administrations over a rolling three-year period. Your percentile indicates the percentage of test takers who scored at or below your score. The tables are updated annually and published on the AAMC website.
A retake is generally worthwhile if you scored below your target range and can identify specific areas for improvement. The AAMC reports that most retakers do improve their scores, but improvement is not guaranteed without a changed study approach. Working with a private tutor like Dr. Donnelly can help you develop a targeted improvement plan that addresses the exact weaknesses in your score report.
Yes. Dr. Stuart Donnelly’s students typically improve by 10–15 points because private tutoring focuses exclusively on your weak areas rather than re-teaching material you already know. By analyzing your score report and diagnostic exams, Dr. Donnelly builds a precise plan that maximizes your score gain per hour of study. This targeted approach is far more efficient than generic courses or self-study.
You can take the MCAT up to 3 times in a single testing year, 4 times across two consecutive years, and 7 times in a lifetime. No-shows and voided exams count toward your attempts. Most medical schools see all of your attempts, which is why preparing thoroughly before each attempt is critical.
