To compute your major (e.g., Psychology) GPA, please follow the following steps:
- List all your psych courses with both Grade and Number of credits (see example table below):
| Course | Grade | Credits |
| Research Methods | B+ | 4 |
| Personality | A- | 3 |
| Social Psych | A | 3 |
| Evolutionary Psych | C | 3 |
2. Create a new column for “weighted GPA” – which will be grade*credits – using the following algorithm for grade:
A = 4.0, A- = 3.67, B+ = 3.33, B = 3.0, B- = 2.67, etc.
| Course | Grade | Credits | Weighted GPA |
| Research Methods | B+ | 4 | 13.32 |
| Personality | A- | 3 | 11.01 |
| Social Psych | A | 3 | 12 |
| Evolutionary Psychology | C | 3 | 6 |
3. Get the sum of the weighted averages (42.33 in this case)
4. Divide that sum by the number of credits (42.33/13 = 3.256)
5. That’s the answer: 3.256
