How your result is calculated
- Grades are percentages, each falling in a letter-grade band; semester and cumulative averages are calculated from the percentage grades.
- Weighted course total = the sum of each course's credit weight multiplied by the grade received. Semester Average = weighted course total ÷ total credit attempts in the semester; Cumulative Average = weighted course total ÷ total credit attempts over all semesters.
- A grade of 0-49 (F) is a fail; a final mark of at least 50% is needed for credit under the Credit/No Credit option.
- Repeated failed course: every attempt stays on the transcript and counts in the semester average. From Summer 2026 on, only the highest grade is used in the cumulative average; this does not apply to courses taken before the Summer 2026 semester.
- Credit/No Credit option: up to 2.00 credits per degree or diploma, on free or liberal education electives only; CR and NCR courses are left out of the semester, cumulative and specialization averages. An NCR still uses up the credits.
- A supplemental assessment does not replace a failing grade: the original grade stays on the record with a P or F notation.
- Two-semester courses count as two course attempts with the same grade for each attempt.
- Exchange courses and some approved courses use the Outstanding/Pass/Fail (OP/P/F) system instead of percentages.

Questions
How is the U of G Semester Average calculated?
Semester Average is the average of your course marks, weighted by credits: multiply each mark by the course's credits, add these up and divide by the total credits. Under Undergraduate percentage grades and averages (no GPA) it is reported out of 100.
Is OpenCGPA an official U of G calculator?
No. OpenCGPA is independent and not affiliated with University of Guelph. It applies the rules published in U of G's own documents, linked on this page. Your official result is the one on your grade card.
