How to Calculate GPA?
To calculate your GPA, divide the total amount of Quality Points earned by the Total Credit Hours attempted.
Example: If you take a 3-credit class and get an 'A' (4.0 points), you earn 12 Quality Points (3 × 4.0). If you take another 2-credit class and get a 'B' (3.0 points), you earn 6 Quality Points (2 × 3.0).
Calculation: (12 + 6) Points ÷ (3 + 2) Credits = 18 ÷ 5 = 3.6 GPA.
