How UB GPA Is Calculated
UB multiplies each grade's point value by the course credit hours to get grade points earned, then divides total grade points by total graded credits.
📝 Worked Example
The official sample calculation from the UB Office of the Registrar:
| Class | Letter Grade | Grade Points Equivalent | Credit Hours | Grade Points Earned |
|---|---|---|---|---|
| English | A | 4.000 | 3 | 3 × 4.000 = 12.000 |
| Physics | B+ | 3.333 | 4 | 4 × 3.333 = 13.332 |
| Chemistry | A− | 3.667 | 3 | 3 × 3.667 = 11.001 |
| World History | C | 2.000 | 3 | 3 × 2.000 = 6.000 |
| Finance | B− | 2.667 | 3 | 3 × 2.667 = 8.001 |
| Total | — | — | 16 | 50.334 |

📌 Grades Excluded from GPA
Only letter grades are used in determining GPA. Marks such as S/U (satisfactory/unsatisfactory), P (pass), I (incomplete), W (withdrawal/resign), and N (audit) carry no grade points and are excluded from graded credits.
An undergraduate course taken S/U converts a grade of C or better to S and C− or lower to U; neither S nor U affects your GPA.
