What GPA Do You Need for Medical School?

Most US MD programs expect a cumulative GPA around 3.7 and a science (BCPM) GPA close to 3.65. DO programs run slightly lower, with matriculants averaging near 3.6 cumulative. If you're below those numbers, you're not out of the race, but you'll need a strong MCAT and a clear upward trend.

The Numbers Admissions Committees Actually See

AAMC data for 2023-2024 MD matriculants shows a mean total GPA of 3.77 and a mean science GPA of 3.68. Applicants (not just matriculants) average lower, roughly 3.62 total and 3.51 science. The gap between applicant and matriculant GPAs is the real story. A 3.5 doesn't sink you, but it puts more weight on your MCAT and your ECs.

For DO schools, AACOM reports 2023 matriculant averages of 3.60 cumulative and 3.52 science. Same principle: solid MCAT and a coherent application can close the gap.

Rough targets by school tier

• Top 20 MD (research-heavy): 3.85+ cumulative, 3.80+ science, MCAT 517+
• Mid-tier MD: 3.65-3.80 cumulative, 3.60+ science, MCAT 510-515
• Lower-tier MD and most DO: 3.50-3.65 cumulative, 3.45+ science, MCAT 505+

These aren't cutoffs. They're where you stop being screened out and start being read.

What Counts as Your Science GPA

BCPM stands for Biology, Chemistry, Physics, and Math. AMCAS calculates your BCPM GPA from every course that fits those four department codes, at every school you've attended, including retakes and community college classes. That last part matters. AMCAS averages both attempts of a repeated course, so a C followed by an A becomes a B in the calculation. Your home school might replace the grade. AMCAS doesn't.

Courses that count:

• Biology: intro bio, cell bio, genetics, microbiology, anatomy, physiology, biochem (usually), ecology
• Chemistry: gen chem, orgo, biochem (sometimes), analytical
• Physics: any physics course, including labs
• Math: calculus, statistics, discrete math, linear algebra

Courses that do NOT count as BCPM: psychology (goes under "social sciences"), most engineering courses, health-science surveys, computer science (unless cross-listed under math).

If you're unsure whether a class counts, check your transcript's department code. AMCAS uses that code, not the course title.

How to Calculate Your BCPM GPA

Convert each grade to a quality-point value, multiply by credit hours, add it all up, divide by total BCPM credit hours.

The AMCAS grade conversion:

• A+ / A = 4.0
• A- = 3.7
• B+ = 3.3, B = 3.0, B- = 2.7
• C+ = 2.3, C = 2.0, C- = 1.7
• D+ = 1.3, D = 1.0, D- = 0.7
• F = 0.0

Worked example

Say you took five BCPM courses freshman and sophomore year:

Total credits: 19. Total quality points: 63.8. BCPM GPA: 63.8 / 19 = 3.36.

Now say you retake Physics I and pull an A (4.0, 16.0 quality points). Under AMCAS: add the retake to the totals rather than replace. New total credits: 23. New quality points: 79.8. BCPM: 79.8 / 23 = 3.47. The retake helps, but not as much as your undergrad registrar would have you believe.

What to Do If Your GPA Is Below Target

• Upward trend beats flat mediocrity. A 3.3 freshman year with a 3.9 senior year reads very differently from a flat 3.6.
• Post-bacc programs (formal or DIY) let you rack up 30+ new science credits at a high level. Adcoms watch these closely.
• Special Master's Programs (SMPs) put you in med-school-level classes. Strong performance is a direct signal.
• MCAT can partially offset GPA. A 515+ with a 3.5 opens doors a 508 with a 3.5 won't.

Don't chase a 4.0 by dropping every hard class. Adcoms read transcripts, not just averages, and a schedule padded with easy A's is obvious.

One More Thing on Retakes

DO schools (through AACOMAS) use grade replacement for repeated courses. MD schools (through AMCAS) don't. If you have a couple of Cs early on and you're leaning DO, a retake can meaningfully lift your reported GPA.
