How Lakehead GPA Is Calculated
Since Lakehead transcripts show letter grades rather than a GPA, a 4.0-scale GPA is estimated using OUAC grade-point equivalents and the standard weighted-average formula.
📝 Worked Example
Suppose a student completes 5 courses with the following grades and credit weights:
| Course | Credits | Letter Grade | Grade Point | Credit Points |
|---|---|---|---|---|
| Course 1 | 1.0 | A+ | 4.0 | 1.0 × 4.0 = 4.0 |
| Course 2 | 1.0 | A | 4.0 | 1.0 × 4.0 = 4.0 |
| Course 3 | 0.5 | B | 3.0 | 0.5 × 3.0 = 1.5 |
| Course 4 | 1.0 | C | 2.0 | 1.0 × 2.0 = 2.0 |
| Course 5 | 0.5 | B | 3.0 | 0.5 × 3.0 = 1.5 |
| Total | 4.0 | — | — | 13.0 |
