Under official Ontario Medical (OMSAS Scale 9) and Law (OLSAS) rules, York University’s 9-point GPA converts course-by-course: a 9 (A+) = 4.00, an 8 (A) = 3.80, a 7 (B+) = 3.30, and a 6 (B) = 3.00. Because York uses no minus grades (no A- or B-), multiplying your 9-point GPA by 4/9 produces severely inaccurate results.
⚡ Quick Answer: York University 9.0 GPA to 4.0 OMSAS Conversion
Never convert a York University 9.0 cumulative GPA with (GPA ÷ 9) × 4. Official Ontario graduate and medical portals (OMSAS Scale 9) convert York grades individually by credit weight: 9 (A+ | 90%+) = 4.00, 8 (A | 80–89%) = 3.80, 7 (B+ | 75–79%) = 3.30, and 6 (B | 70–74%) = 3.00.

3. Official York 9.0 Scale to OMSAS 4.0 & Percentage Chart
York University uses a distinctive 10-step grading system (0 through 9) documented as Scale 9 in the official Ontario Medical School Application Service (OMSAS) and Ontario Law School Application Service (OLSAS) tables:
| York Letter Grade | York 9.0 Value | Percentage Benchmark | OMSAS 4.0 Value | US AMCAS Scale |
|---|---|---|---|---|
| A+ | 9 | 90% – 100% | 4.00 | 4.00 |
| A | 8 | 80% – 89% | 3.80 | 4.00 |
| B+ | 7 | 75% – 79% | 3.30 | 3.30 |
| B | 6 | 70% – 74% | 3.00 | 3.00 |
| C+ | 5 | 65% – 69% | 2.30 | 2.30 |
| C | 4 | 60% – 64% | 2.00 | 2.00 |
| D+ | 3 | 55% – 59% | 1.30 | 1.30 |
| D | 2 | 50% – 54% | 1.00 | 1.00 |
| E / F | 1 / 0 | 0% – 49% (Fail) | 0.00 | 0.00 |
4. The “No Minus Grades” Advantage & Why (GPA ÷ 9) × 4 Fails
Unlike U of T, McMaster, or Western, York University awards NO minus grades (no A-, B-, C-, or D-). An 80% score and an 89% score both appear identically as an A (8) on a York transcript.
- The 80–84% Windfall: At U of T or McMaster, an 82% gives you an A- (3.70 OMSAS). At York University, that same 82% earns an A, converting to 3.80 OMSAS (and 4.00 US AMCAS).
- Why (GPA ÷ 9) × 4 Destroys Your Standing: If you earn an 8.0 / 9.0 average (straight As), naive proportional scaling gives
(8 ÷ 9) × 4 = 3.56—making you look like a B+ student when your real OMSAS medical school GPA is 3.80.

| 7.50 | 3.55 – 3.65 | B+ / A Mix | Magna Cum Laude & Competitive Master’s / MBA |
| 7.00 | 3.30 | Solid B+ Average | Cum Laude honours; graduate admissions minimum |
6. Schulich Business & Osgoode Hall Law School Admissions Rules
York University houses two of Canada’s highest-ranked professional faculties, each handling Scale 9 conversions distinctly:
- Osgoode Hall Law School (OLSAS): Uses the exact Scale 9 mapping (9=4.0, 8=3.8, 7=3.3). For internal York applicants, a 7.8–8.2 cGPA alongside a competitive LSAT aligns with Osgoode’s median entering cohort (~3.75–3.80 OLSAS GPA).
- Schulich School of Business (MBA / BBA): Accepts the native 9.0 scale internally, requiring a minimum B average (6.0 on York’s scale, or 3.00 OMSAS equivalent) across the final two years of undergraduate study for postgraduate admissions.
