McMaster does not use a 4.0 scale for internal GPA; the 12-point system is used for all course grades and cumulative averages.

📐 How to calculate cumulative GPA at McMaster (Step-by-Step)

Your cumulative GPA (cGPA) is the weighted average of all courses taken at McMaster. Use this formula:

cGPA = (Σ (Grade Points × Credit Hours)) / (Σ Credit Hours)
  1. Multiply each course's grade points (12‑point scale) by its unit weight (credit hours).
  2. Sum all quality points.
  3. Divide by total credit hours attempted (including failed courses).

Pro tip: McMaster Med School calculates cGPA based on all undergraduate courses (no dropping). Use our cumulative GPA calculator McMaster above to simulate different scenarios.

🏥 McMaster Med GPA Calculation: What you need for 2026 admission

Michael G. DeGroote School of Medicine (McMaster Med) evaluates applicants using cumulative GPA (cGPA) on the 12‑point scale. They do not apply weighting formulas; every undergraduate course counts. The minimum competitive cGPA for 2026 interviews is generally 3.85+ (converted to 4.0 scale) ≈ 10.8+ on McMaster 12‑point scale. However, successful applicants often have 11.0+ (A- to A average).

  • Original insight: McMaster’s admissions uses CASPer and CARS (MCAT) in addition to GPA, but a strong cGPA (above 10.5) remains critical.
  • 2026 trend: The average accepted cGPA (12‑point) is approx 10.9–11.2. Use our calculator to project how future courses affect your cumulative GPA.
  • Exclusive checklist: Re-take only D/F courses? McMaster repeats are both included in cGPA; original grade stays on transcript. Focus on earning A-/A in high-credit courses to boost GPA faster.

📋 Example: Term GPA vs Cumulative effect

Term GPA: (30+27+33+36) / (3+3+3+3) = 126 / 12 = 10.5 (A- average). If prior cumulative GPA was 9.8 with 48 credits, new cumulative = (9.8×48 + 126) / (48+12) = 596.4 / 60 = 9.94 – our calculator does it instantly.
