How Your GPA Is Calculated
Your GPA is calculated using the following formula:

Where:
- Grade Point is the numeric value assigned to each letter grade
- Credit Value is the weight of each course (typically 1.0)
The Ontario high school grading system uses the following grade points:
| Letter Grade | Grade Point | Percentage Range |
|---|---|---|
| A+ | 4.3 | 97-100% |
| A | 4.0 | 93-96% |
| A- | 3.7 | 90-92% |
| B+ | 3.3 | 87-89% |
| B | 3.0 | 83-86% |
| B- | 2.7 | 80-82% |
| C+ | 2.3 | 77-79% |
| C | 2.0 | 73-76% |
| C- | 1.7 | 70-72% |
| D+ | 1.3 | 67-69% |
| D | 1.0 | 63-66% |
| F | 0.0 | Below 63% |

Example Calculation
Let's calculate a GPA for a student who took three courses:
- English: 88% (B+)
- Mathematics: 92% (A-)
- Science: 75% (C)
Using the grade conversion table:
- English: 3.3 grade points
- Mathematics: 3.7 grade points
- Science: 2.0 grade points
The GPA calculation would be:
GPA = (3.3 + 3.7 + 2.0) / 3 = 9.0 / 3 = 3.0
This student would have a GPA of 3.0 for these three courses.
