GPA = Σ (GradePoints_i × Credits_i) ÷ Σ Credits_iIn South Korea, academic evaluation commonly uses percentage grades or institutional letter equivalents. Scores of 90% or above correspond to an American 4.0 (A), 80–89% to 3.0 (B), and 70–79% to 2.0 (C). Cumulative GPA is calculated by multiplying each course grade point by its credit value, dividing the total quality points by total credits.
Examples
Sample Coursework in South Korea (12 Credits Total)
Course 1: 92% (Grade A → 4.0 GPA, 6 credits) → Quality Points = 4.0 × 6 = 24.0
Course 2: 82% (Grade B → 3.0 GPA, 6 credits) → Quality Points = 3.0 × 6 = 18.0
Total Quality Points = 24.0 + 18.0 = 42.0 ÷ 12 credits.
Estimated US GPA: 3.50
