Hong Life CalculatorsHow OMSAS calculates your GPA
- Each course grade is converted to the OUAC 4.0 value using the scale for your university (percentage scale below).
- Each converted grade is multiplied by the course weight: full-year 2, half-year/semester 1, three-quarter 1.5, lab 0.5.
- The cumulative GPA = total converted points ÷ total course weights — not an average of yearly averages.
| Percentage | Letter | OUAC 4.0 value |
|---|---|---|
| 90–100 | A+ | 4.0 |
| 85–89 | A | 3.9 |
| 80–84 | A− | 3.7 |
| 77–79 | B+ | 3.3 |
| 73–76 | B | 3.0 |
| 70–72 | B− | 2.7 |
| 67–69 | C+ | 2.3 |
| 63–66 | C | 2.0 |
| 60–62 | C− | 1.7 |
| 57–59 | D+ | 1.3 |
| 53–56 | D | 1.0 |
| 50–52 | D− | 0.7 |
| 0–49 | F | 0.0 |
Worked example (default inputs): 88% full-year (3.9 × 2) + 82% (3.7) + 91% (4.0) + 76% (3.0) + 85% full-year (3.9 × 2) + 79% (3.3) = 29.6 points ÷ 8 weights = 3.70.
OMSAS counts all undergraduate courses on your transcripts, including failures and repeated courses. Pass/credit courses, college courses, graduate courses, IB/AP credit and challenge-for-credit courses are normally excluded. Each medical school may also apply its own GPA rules (for example dropping lowest years).
FAQ
How is the OMSAS GPA calculated?
Convert every course grade to the OUAC 4.0 value, multiply by the course weight (full-year 2, half-year 1) and divide the total by the total weight.
What is 85% on the OMSAS scale?
3.9 on the percentage scale (85–89%). 90% and above is 4.0, and 80–84% is 3.7.
Does OMSAS include failed or repeated courses?
Yes. All attempts shown on your official transcript are included in the cumulative GPA.
