Guelph GPA scale
University of Guelph 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 Guelph’s admission requirements are on their own page.

How Guelph computes your average
Grades are percentages; the letters are the calendar's bands on them. Averages are percentage averages.
Worth knowing before first year
- Guelph's thirteen letter bands are the same widths as the 4.3/12-point universities — but Guelph never converts them to points. Your average stays a percentage.
The same mark at other campuses
Where a 95, 85, 78, 72, 65 lands at Guelph 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.
