How GPA is calculated
Your GPA is the weighted average of your grades, with each course weighted by its credit hours.
Grade Points = Grade Value × Credit Hours
Example: You have three courses this semester:
- Course 1: A (4.0) × 3 credits = 12 grade points
- Course 2: B+ (3.3) × 3 credits = 9.9 grade points
- Course 3: A- (3.7) × 4 credits = 14.8 grade points
Total: 36.7 grade points / 10 credits = 3.67 GPA
