Med school applications split your transcript into two numbers: the overall GPA everyone knows, and the science GPA — BCPM — that admissions committees scrutinize hardest. Enter your courses below, check the BCPM box on your biology, chemistry, physics, and math classes, and see both GPAs side by side, computed the credit-weighted way AMCAS does it.

BCPM stands for Biology, Chemistry, Physics, and Math — the four departments AMCAS pools into your science GPA (often written sGPA). When AMCAS verifies your application, it classifies every course on your transcript, then computes two credit-weighted averages: the BCPM GPA from science and math coursework, and the AO ("all other") GPA from everything else. Most labs attached to BCPM lecture courses land in the BCPM pool too.
Committees care about the split because the sGPA isolates your performance in exactly the kind of coursework medical school is made of. A transcript can carry a shiny overall GPA on the strength of non-science electives; the BCPM number strips that away.
Classification follows course content, not your major and not always the course title. The broad strokes:
| Category | Examples |
|---|---|
| Counts as BCPM | Biochemistry, genetics, statistics, anatomy & physiology, and most biology/chemistry/physics labs |
| Doesn't count | Psychology, sociology, nursing and health-science courses, and biomedical engineering (usually classified as engineering) |
| Borderline | Neuroscience and exercise physiology — depends on the specific course's content and department |
The three application services compute science GPAs with slightly different rules. AMCAS (MD programs) includes every attempt of every course, averaged with no grade replacement. AACOMAS (DO programs) once let retakes replace original grades, but ended that policy in 2017 and now averages all attempts too. TMDSAS (Texas public medical and dental schools) runs its own course categories and its own GPA calculation, so your numbers can differ slightly across services even from the same transcript. This calculator follows the AMCAS averaging convention.
| Applicant pool | Overall GPA | Science GPA |
|---|---|---|
| MD matriculants | ~3.7 | ~3.6 |
| DO matriculants | ~3.5 | ~3.4 |
| Below 3.0 sGPA | Usually needs postbac or SMP coursework to be competitive |
These are averages, not cutoffs — applicants get in below them and get rejected above them every cycle. But they anchor the honest conversation: an sGPA under 3.0 usually calls for additional coursework, through a postbaccalaureate program or a special master's program (SMP), before the application is competitive.
Committees read the two GPAs together, and a large gap in either direction draws attention. A cumulative GPA far above the science GPA suggests science coursework is the weak spot — the worst place for a premed to be weak. The reverse gap, science well above overall, invites questions about the non-science grades. Ideally the two travel close together, and where they don't, trajectory matters: recent, rigorous science performance counts most.
