How is a weighted college GPA calculated?

Each course grade is assigned grade points on a 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0). Multiply each course's grade points by its credit hours to get quality points, sum all quality points, and divide by the total number of credit hours attempted.
