Understanding MCAT scoring, scaled scores, percentiles, and what med schools are actually looking for.
“I Got a 508 — Is That Good?”
If you’ve ever typed your MCAT score into Reddit or a student forum, you’ve probably seen a flood of conflicting responses:
“508? That’s low.”
“It depends on your school list!”
“CARS probably dragged it down.”
“Solid score, but try again if you’re applying MD-PhD.”
So — what do your MCAT scores really mean? In this post, we’ll break down how the AAMC scores the MCAT, what percentiles really say about your performance, and how admissions committees actually interpret your score in the context of the entire application. Whether you’re scoring in the 490s or the 520s, understanding this framework is essential to making informed decisions.
MCAT Scoring — The Basics
The MCAT is scored across four sections:
| Section | Score Range |
| Chemical & Physical Foundations (CP) | 118–132 |
| Critical Analysis & Reasoning Skills (CARS) | 118–132 |
| Biological & Biochemical Foundations (BB) | 118–132 |
| Psychological, Social, & Biological Foundations (PS) | 118–132 |
These scores are summed to give a total score ranging from 472 to 528, with 500 representing the mean.
Each section’s score is scaled from your raw score (i.e., number correct), but this scaled score reflects item difficulty and test form, not just percent correct. That’s why a 125 might mean getting 60% of the questions right on one form and 70% on another.
Important: You are not penalized for wrong answers — always guess!
What Is a “Good” MCAT Score?
This depends entirely on your goals and school list.
| Score Range | General Interpretation |
| 520+ | Exceptional (98th–100th percentile); top-tier MD programs |
| 515–519 | Very strong (94th–97th); competitive across most MD schools |
| 510–514 | Solid (80th–93rd); strong candidate for many MD programs |
| 505–509 | Adequate (65th–79th); viable for DO and some MD programs |
| 500–504 | Below average for MD, but viable for DO and special programs |
| <500 | Needs improvement; retake strongly recommended unless extenuating circumstances |
MCAT score percentiles are updated annually. As of the 2024 data, a 501 is approximately the 47th percentile, and a 510 is about 80th percentile. A full and comprehensive MCAT percentile chart can be obtained here.
Pro Tip: Percentile ≠ raw MCAT score. It’s about where you rank relative to other test takers, not how many you got “right.”
The CARS Conundrum
CARS is notoriously tricky — and heavily weighted at certain schools.
A few key facts:
- CARS scores tend to average lower than science sections.
- Even top scorers often report a CARS of 125–127.
- Schools like UCLA, UCSF, and the Mayo Clinic School of Medicine have historically emphasized strong CARS performance.
If you scored lower in CARS, don’t panic — just balance it with stronger science sections or demonstrate strong verbal skills in your essays and interviews.
Understanding Confidence Bands and Score Profiles
Each section score includes:
- A confidence band (±1 score point)
- A percentile rank
- A total score
Admissions committees understand that your actual ability lies within the confidence band, not at a pinpointed number.
Example:
An MCAT score of 508 with a CARS 124 might not be ideal — but if the rest of the application is strong (GPA, research, leadership, LORs), many schools will still view you as a solid candidate.
How Admissions Committees Evaluate MCAT Scores
Medical schools don’t evaluate scores in a vacuum. They use a holistic review, which may include:
- Undergraduate GPA (especially BCPM)
- MCAT score profile (section balance matters!)
- Upward trends in GPA or scores
- Fit with mission (rural medicine, research, diversity)
- Personal statement, LORs, clinical and research experience
- Background and context (e.g., first-gen, reapplicant, adversity)
MD-PhD tip: Most MSTPs expect a minimum of 515, with competitive candidates scoring 518+, especially in CP and BB.
Should You Retake?
Ask yourself:
| Question | Consider Retaking If… |
| Did I score well below the median of my target schools? | Yes |
| Was my score significantly unbalanced (e.g., 129/128/124/130)? | Possibly |
| Did I have extenuating circumstances (illness, stress)? | Possibly |
| Am I consistently scoring much higher on FL exams? | Yes |
| Did I already have strong GPA, research, and ECs? | Maybe not |
Rule of Thumb: Retake only if you’re confident you can improve your MCAT score by 3+ points — and if your current score clearly places you below your school list’s target range.
Your MCAT Score Is Part of the Story
The MCAT is an important hurdle — but it’s not your whole application. A balanced, well-executed application with a strong personal narrative, meaningful clinical experience, and solid letters can absolutely overcome a sub-515 score.
Your job is to understand what your score means, be honest about your goals, and make strategic decisions — not panic or compare yourself to Reddit noise.
