- 126
- Psych / Soc

Section medians are projected from the total using the publicly published national section distribution (CARS runs lowest, Psych/Soc highest). Schools rarely publish their own per-section medians, so this is an estimate; real values are shown when we've sourced them.
vs US DO matriculants: MCAT -1.5 (nat. 503.5), GPA -0.07 (nat. 3.60).
MCAT range by residency Premier estimate
| Matriculants | 10th | 25th | 75th | 90th |
|---|---|---|---|---|
| Combined | 495.6 | 498.4 | 506.2 | 510.1 |
| In-state | 497.2 | 499.9 | 508.4 | 511.8 |
| Out-of-state | 497.3 | 500.2 | 507.9 | 511.8 |
The box spans the 25th–75th percentile; the whiskers reach the 10th and 90th. Premier's model estimates the full spread and the residency split from the published median, using its out-of-state share — calibrated across every US MD program and validated to within ~1.5 points of reported figures. Estimates are shown to one decimal. How this works.

Course exams
Core clerkship exams are the NBOME's standardized COMAT subject exams — standardized nationally, so they're consistent across DO schools. Whether the preclinical years lean on in-house, NBME-based, or a mix of exams isn't something schools publish in one place — so we don't guess per school; confirm specifics with the school.
