OMSAS GPA explained for medical-school applicants

Ontario medical schools don't use your university's GPA directly. The Ontario Medical School Application Service (OMSAS) recomputes every applicant's record onto its own 4.0 OMSAS scale so all applicants are compared on one ruler.

How the OMSAS conversion works

OMSAS maps your percentage grades to grade points using a published table — for example 90–100% = 4.0, 85–89% = 3.9, 80–84% = 3.7, and downward in fixed bands. Every course is converted, then credit-weighted into your OMSAS GPA.

Why it can differ from your transcript GPA

Because OMSAS uses its own band table rather than your university's letter mapping, the number can come out slightly higher or lower than the GPA your school prints. Two applicants with the same transcript percentages get the same OMSAS GPA regardless of which university they attended.

What OMSAS counts

OMSAS generally converts all attempted undergraduate courses; individual schools then apply their own weighting (some drop your lowest year or weight recent years). Check each school's policy on top of the base OMSAS GPA.

Key takeaways

• OMSAS converts your percentages to its own 4.0 scale via a fixed band table.
• The OMSAS GPA can differ from your university's printed GPA.
• It levels applicants from different schools onto one scale.
• Individual med schools may re-weight on top of the base OMSAS GPA.
