What GPA does each letter grade correspond to?

A+ and A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, F = 0.0. This is the standard scale used by most U.S. colleges.

How is weighted cumulative GPA calculated?

Each course earns quality points equal to its grade points multiplied by its credit hours. Cumulative GPA is the sum of all quality points divided by the total credit hours. For example, a B (3.0) in a 4-credit course contributes 12.0 quality points.

Most colleges do not use D- as a passing grade and assign it 0.7 points. This tool omits D- because the majority of institutions treat D as the lowest passing mark (1.0) and F as failing (0.0).
