How it works
Each letter grade converts to grade points (A = 4.0, B = 3.0, and so on), gets multiplied by that course's credit hours, then the total is divided by total credit hours. For example, an A in a 4-credit course and a B in a 3-credit course gives (4×4 + 3×3) / 7 = 3.57 — courses with more credit hours count more toward the average.
