How GPA is calculated
Your Grade Point Average is the weighted average of the grade points you earn across all your courses, weighted by each course's credit hours.
GPA = (Sum of Grade Points × Credits) / Total Credits
Worked example
Suppose you take three courses: an A (4.0 points) worth 3 credits, a B+ (3.3 points) worth 4 credits, and a C (2.0 points) worth 3 credits.
(4.0 × 3) + (3.3 × 4) + (2.0 × 3) = 12 + 13.2 + 6 = 31.2
Total credits = 3 + 4 + 3 = 10
GPA = 31.2 / 10 = 3.12
