How to Calculate Your GPA
Your GPA is a weighted average of your grades, where each course is weighted by its credit hours. Here's the formula:
GPA = Total Grade Points ÷ Total Credit Hours
Grade Points for a course = Grade Point Value × Credit Hours
Example: A (4.0) in a 3-credit course = 12.0 grade points
Example calculation: You took three courses this semester — Biology (A, 4 credits), English (B+, 3 credits), and Math (B−, 3 credits).
Biology: 4.0 × 4 = 16.0 points
English: 3.3 × 3 = 9.9 points
Math: 2.7 × 3 = 8.1 points
─────────────────────────────
Total: 34.0 points ÷ 10 credits = 3.40 GPA
