Cumulative GPA

Estimate only. OMSAS, OLSAS and each university calculate their own official GPA, and some schools use only selected years or courses.

Get expert help OUAC converts each grade on its own, using the scale assigned to your university, then averages the converted grades weighted by course length. A full-year course counts twice as much as a half-year course. This is a course-weighted average, not an average of yearly averages.

Worked example Five Queen's University courses with percentage grades, so Scale 3 applies:
Course Grade Length 4.0 value Weight Weighted Biology 86 Full year 3.90 2 7.80 Chemistry 78 Half year 3.30 1 3.30 Psychology 91 Half year 4.00 1 4.00 Calculus 72 Half year 2.70 1 2.70 Chemistry lab 88 Lab 3.90 0.5 1.95
Total weighted points: 19.75. Total weight: 5.5. GPA: 19.75 / 5.5 = 3.59.

Universities outside Ontario are also on the OUAC table. See the full OUAC Undergraduate Grade Conversion Table .
Both services use the OUAC table and the 4.0 scale. OMSAS (medical school) includes failed, repeated and supplementary courses, and courses beyond your degree requirements. It leaves out pass or credit grades, graduate courses, and IB and AP grades. Where a transcript shows both a percentage and a letter, OMSAS uses the percentage, except for UBC, where it uses the letter. Each medical and law school can also calculate its own GPA, so check the school's admissions page.
For the full rules, see our percentage to GPA guide .
These are the OUAC scales this calculator applies. Percentage ranges use whole numbers.

What is the OUAC GPA scale? OUAC converts university grades to a 4.0 scale using one conversion table with several scales. Most Ontario universities use Scale 3 for percentage grades and Scale 7 for letter grades. York uses Scale 9.
Is an 85 an A in Ontario? On OUAC Scale 3, a grade from 85 to 89 converts to 3.90 on the 4.0 scale. A grade of 90 or higher converts to 4.00.
Does OMSAS use the same calculation? OMSAS uses the OUAC conversion table and the same course weights as this calculator. It also includes failed and repeated courses and leaves out pass or credit grades, graduate courses, and IB and AP grades.
Why is my calculated GPA different from my university's GPA? Universities often report GPA on their own scales, such as a 4.3 or 9-point scale, and may round differently. OUAC converts each course separately to its 4.0 scale, so the two numbers can differ.
Is this calculator official? No. It applies the published OUAC table to the grades you enter, but OUAC, OMSAS, OLSAS and each university make the official calculation.
