Waterloo GPA scale
University of Waterloo has no letter grades and no GPA: every course is marked out of 100 and your standing is a percentage average. Here is what the calendar says about how that average is built.
This is the scale you are graded on once you arrive. It is not the average you are admitted on — Ontario universities admit on your Grade 12 percentage average, and Waterloo’s admission requirements are on their own page.

What passes at Waterloo
The calendar's grading regulations do not print a single passing number; Waterloo's faculty pages give 50 as the pass in a course.
How Waterloo computes your average
“All faculties use numeric grades on a scale from 0 to 100.” “Averages are reported in all faculties as percentages.” “Any grade between 0 and 32 is treated as having a value of 32 when averages for promotions and awards are calculated.”
Worth knowing before first year
- No letters, no GPA — a Waterloo transcript is numbers, and your standing is a percentage average.
- A catastrophic mark is floored: anything from 0 to 32 counts as 32 in the averages used for promotion and awards.
The same scale applies at St. Jerome's and Renison.
