AMCAS GPA scale and grading policy
Quick answer: American Medical College Application Service (AMCAS GPA) uses the amcas recalculates undergraduate gpa on a standard 4.0 scale and separates science gpa (bcpm: biology, chemistry, physics, math) from non-science gpa. every grade from every transcript counts — including retakes (both attempts). AMCAS does NOT replace grades for retaken courses (unlike most undergrad institutions). Both attempts are averaged into the AMCAS GPA. AP credit is excluded from AMCAS GPA. The recalculated GPA is what medical schools use, not your school's reported GPA.
| Metric | AMCAS Standard |
|---|---|
| Typical admit GPA | Top med schools: 3.8 - 3.9 AMCAS GPA + 3.8+ Science GPA |
| Good standing minimum | 3.0 (typical pre-med floor) |
| Dean's List threshold | 3.7+ AMCAS GPA for competitive medical school admission |
| Scale type | AMCAS recalculates undergraduate GPA on a standard 4.0 scale and separates Science GPA (BCPM: Biology, Chemistry, Physics, Math) from non-Science GPA. Every grade from every transcript counts — including retakes (both attempts). |
How AMCAS recalculates GPA for admission
AMCAS does NOT replace grades for retaken courses (unlike most undergrad institutions). Both attempts are averaged into the AMCAS GPA. AP credit is excluded from AMCAS GPA. The recalculated GPA is what medical schools use, not your school's reported GPA. The number you submit on your transcript and the number AMCAS uses in its admission decision may differ. Use the calculator above to model both — switch the preset to match AMCAS's policy.
Maintaining a good AMCAS GPA
- Science GPA matters as much as overall. Med schools view a 3.95 overall with 3.6 science as red-flag — they read it as "strong humanities student who struggles with hard sciences." Aim to keep Science GPA within 0.1 of overall.
- AP credit doesn't help your AMCAS GPA. AP credit gets you out of intro coursework but doesn't add to AMCAS GPA. If you skipped intro bio with AP, take it again in college — adcoms specifically look for the upper-division equivalent.
- Post-bacc is the recovery path. If your AMCAS GPA is below 3.5, a structured post-baccalaureate program (1-2 years of full-time science courses with 3.8+ post-bacc GPA) is the standard rebuild — better than scattered community-college courses.
