Windsor GPA scale
University of Windsor records percentages, not grade points. The letters below are the bands its calendar draws on those percentages — an A starts at 90% — with the passing grade and how the average is computed.
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 Windsor’s admission requirements are on their own page.

How Windsor computes your average
“The University of Windsor uses a percentage marking and grading scale. Course instructors are to assign and record integer-valued grades, and these grades are to be considered the exact assigned grades earned by the students.” “Averages are rounded to the nearest one-hundredth.”
Worth knowing before first year
- Windsor switched from a thirteen-point system to percentages in Fall 2013; the letter table exists “for the use of external readers” on the back of the transcript.
- The same percentage that is a D+ for an undergraduate is an F for a graduate student (57–59.9).
The same mark at other campuses
Where a 95, 85, 78, 72, 65 lands at Windsor and at the other universities that publish percentage bands. Useful when comparing scholarship-renewal or program-entry thresholds written in different currencies.

Waterloo is not in the table: it has no letters, so a 78 is a 78.
