How GPA is Calculated
GPA is the weighted average of your grades, factoring in course credit hours. The formula is:
GPA = (Total Grade Points Earned) ÷ (Total Credit Hours)
Example 1:
| Course | Credits | Grade | Calculation |
|---|---|---|---|
| Math | 4 | A+ | 4 × 4.3 = 17.2 |
| Physics | 2 | B | 2 × 3.0 = 6 |
| English | 3 | A | 3 × 4.0 = 12 |
| Total | 9 | — | 35.2 ÷ 9 = 3.91 GPA |
Example 2 (Numerical Grades):
| Course | Credits | Score | Calculation |
|---|---|---|---|
| Biology | 4 | 3 | 4 × 3 = 12 |
| Chemistry | 3 | 2 | 3 × 2 = 6 |
| Chemistry Lab | 2 | 4 | 2 × 4 = 8 |
| Total | 9 | — | 26 ÷ 9 = 2.89 GPA |
