GPA Calculator

McMaster uses a 12-point scale (A+ = 12 … F = 0). Your GPA is the credit-weighted average of those points across all courses attempted. The Registrar lists the official 12-point mapping and percentage ranges.

GPA types at McMaster

You’ll look at a term/semester GPA (one term) and a cumulative GPA (cGPA) across your McMaster coursework. Note: McMaster’s official transcript does not display a cumulative GPA (the transcript legend explains the scale); use term summaries or your own calculation for cGPA.

Find my GPA in Mosaic

In Mosaic → Student Centre, check Academics → Grades for term results, or view/download your Unofficial Transcript to see all final grades in one place (official record). Some summaries show cumulative totals; otherwise calculate using the 12-point table below.

Letter grade	Percentage range	Grade points (12-pt)
A+	90–100	12
A	85–89	11
A−	80–84	10
B+	77–79	9
B	73–76	8
B−	70–72	7
C+	67–69	6
C	63–66	5
C−	60–62	4
D+	57–59	3
D	53–56	2
D−	50–52	1
F	0–49	0

GPA and academic standing

Standing rules are faculty-specific, but your cGPA is the key driver. Examples: many Honours B.Sc. programs require cGPA ≥ 5.0 to continue/graduate; Engineering materials commonly reference cGPA ≥ 4.0 to remain in the program (university continuation minima may differ). Always confirm your program’s calendar/advising pages.
