Brock University GPA Calculator & Percentage Converter

Q: What grading scale does Brock University use?

Brock University records grades as percentages with corresponding letter grades (A, B, C, D, F). For GPA purposes the percentage is mapped to a 4.0 scale using the official OUAC Grade Conversion Table, where 90–100% = 4.0, 85–89% = 3.9, 80–84% = 3.7, and so on.

Q: How do I convert a Brock percentage to a 4.0 GPA?

Match your course percentage to the OUAC band. For example, 90–100% = 4.0, 73–76% = 3.0, 60–62% = 1.7, and 0–49% = 0.0. Average the grade points weighted by credit value to get your GPA.

Q: What is the minimum grade used in Brock average calculations?

For average calculations only, an F grade of 45% or lower is counted as 45%, while an F of 46-49 keeps its actual value. Passing grades are used as earned, and transcripts always show the actual mark.

Q: How does graduate grading differ from undergraduate at Brock?

Undergraduate uses A, B, C, D, F with a pass at 50%. Graduate adds an A+ band (90-100) and sets a higher bar: while A+, A, B and C are passing, most programs grant credit only for A+, A and B, and an F is 59% or lower.

The Math

How Brock GPA Is Calculated

Each course percentage is converted to a 4.0 grade point, then averaged by credit value.

Brock GPA Formula

\[ \text{GPA} = \frac{\displaystyle\sum (\text{Grade Point} \times \text{Credits})}{\displaystyle\sum \text{Credits}} \]

Grade PointOUAC 4.0 value mapped from the percentage (0.0–4.0)

CreditsCredit value of each course (typically 0.5 or 1.0)

📝 Worked Example

Suppose a student completes 4 courses with the following percentages and credit values:

Course	Credits	Percentage	Grade Point	Credit Points
Course 1	1.0	92	4.0	1.0 × 4.0 = 4.00
Course 2	0.5	78	3.3	0.5 × 3.3 = 1.65
Course 3	1.0	74	3.0	1.0 × 3.0 = 3.00
Course 4	0.5	61	1.7	0.5 × 1.7 = 0.85
Total	3.0	—	—	9.50

Plugging into the formula:

\[ \text{GPA} = \frac{9.50}{3.0} \approx \mathbf{3.17} \]

How the Conversion Works

Brock does not use a fixed multiplier — each percentage falls into an OUAC band that has a fixed 4.0 grade point:

Example: A mark of 78% falls in the 77–79 band, which equals a grade point of 3.3 (letter grade B).

📘 Official Brock Undergraduate Letter Grades

The grades awarded for undergraduate courses, per the Brock University Academic Regulations.

Percentage	Letter Grade	Performance
90–100	A	Outstanding — superior work that exceeds expectations
80–89	A	Excellent — comprehensive and accurate work
70–79	B	Competent — sound grasp of the course; meets expectations
60–69	C	Adequate — average competence below a B standard
50–59	D	Marginal — barely satisfies minimum requirements
49 or lower	F	Fail — no formal credit

A pass is 50%. Brock records the actual numeric mark on the transcript. For average calculations only, an "F" of 45 or lower is counted as 45%; an "F" of 46–49 keeps its actual value.

🎓 Official Brock Graduate Letter Grades

Graduate courses use a different scale with a higher pass threshold, per the Brock University Graduate Calendar.

Percentage	Letter Grade	Graduate Credit
90–100	A+	Yes
80–89	A	Yes
70–79	B	Yes (minimum for credit)
60–69	C	No credit unless specified
59 or lower	F	No credit (fail)

A+, A, B and C are passing grades, but most graduate programs grant credit only for A+, A and B. Many programs also require an overall minimum B average to graduate.
