Calculate the AMCAS GPA medical schools will see: the official AAMC conversion table (A+ capped at 4.0), every repeated attempt counted, WF treated as F, and the BCPM science and All Other split explained.
| Grade | Credit hours |
|---|
Enter every attempt of every graded undergraduate course, including repeats, AMCAS computes both the original grade and the retake into the GPA. Tag WF as WF, plain W and pass/fail grades simply stay out.
| Grade | Grade points | AMCAS treatment |
|---|---|---|
| A+ | 4.0 | Capped at 4.0, the same as an A, even if your school awards 4.33 |
| 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 | Counted, even if your school excludes it |
| WF | 0.0 | Withdrawal-failing, AMCAS treats it as an F; a plain W is excluded |
| Input | Result |
|---|---|
| A (4cr) + B+ (4cr) + A− (4cr) + B (3cr) | 3.53 / 4.00 |
| F (4cr) retaken for an A (4cr) | 2.00 / 4.00, both attempts count; grade replacement does not exist in AMCAS |
| A+ (3cr) + A (3cr) + C (3cr) | 3.33 / 4.00, the A+ is capped at 4.0, so it adds nothing over the A |
| B+ (3cr) + W (3cr) + P (3cr) | 3.30 / 4.00, W and pass/fail hours are excluded from both sides |
AMCAS does not report a single average. It converts your transcript onto its standard scale and then splits the coursework three ways, so the number a medical school stares at depends on which bucket a course lands in:
| GPA | Which courses | What admissions reads from it |
|---|---|---|
| Science (BCPM) | Biology, Chemistry, Physics and Mathematics, classified by course content, not department name | Readiness for the medical school curriculum; a low BCPM with a high Total GPA is a red flag med schools notice |
| All Other (AO) | Everything that is not BCPM | Consistency outside the sciences |
| Total | Every graded undergraduate course, repeats included | The headline number, reported by year and cumulatively |
To estimate your Science GPA with this calculator, run it once with only your BCPM courses and once with everything, the first result approximates BCPM, the second the Total. Statistics counts as Mathematics; health science, nursing and exercise physiology courses generally do not. When a classification is genuinely ambiguous, AMCAS's verifier can reclassify the course, which shifts your Science GPA without moving the Total.
| Cause | Size of the gap |
|---|---|
| Repeats: both attempts count, while most schools replace the grade | Commonly 0.2–0.5 GPA points for applicants with several retakes |
| A+ capped at 4.0 on a 4.33 school scale | 0.05–0.15 points for applicants with many A+ grades |
| Graded courses your school excluded (learning-support, PE) | Small, but nonzero |
| Entry | What AMCAS does instead |
|---|---|
| W (plain withdrawal), audits | No value, no weight, simply not computed |
| Pass / Credit / Satisfactory | Excluded from the GPA; the hours are reported as Supplemental Hours |
| AP and CLEP credit | Excluded; reported as Supplemental Hours |
| Graduate coursework | Reported in a separate Graduate GPA, not mixed into the undergraduate figure |
The conversion weights and the treatment of repeats, WF, W, pass/fail and AP credit come from the AAMC's AMCAS Grade Conversions document and the AMCAS Applicant Guide's grades-and-GPA tables. AMCAS recalculates from official transcripts during verification, so treat this as the estimate to check your entries against, the verified figure is authoritative.
AMCAS converts every graded undergraduate course onto its own 4.0 scale (A+ capped at 4.0, A− 3.7, down to F at 0.0), multiplies by credit hours, sums, and divides by graded credit hours. Every attempt of a repeated course is included, there is no grade replacement.
No. AMCAS caps A+ at 4.0, identical to an A. Applicants from schools that award 4.33 for an A+ often see their GPA drop slightly in the AMCAS recomputation for exactly this reason.
Both the original grade and the retake enter the GPA calculation, the numerator and the denominator each carry every attempt. This is the single most common reason an AMCAS GPA comes in below the transcript GPA.
BCPM is the Science GPA: Biology, Chemistry, Physics and Mathematics courses, classified by content. AO (All Other) covers every non-science course. AMCAS reports both plus the Total, each broken down by year in school.
Pass grades, plain W withdrawals and AP credit are excluded from the GPA and reported separately as Supplemental Hours. But a fail under a pass/fail system, an F, or a WF (withdrawal-failing) is computed as 0.0 with full credit-hour weight.
