How your Ohio State GPA is calculated

GPA = total quality points ÷ total graded credit hours, where quality points for a course = grade points × credit hours. For a new cumulative GPA: (current GPA × hours so far + this term’s quality points) ÷ (hours so far + this term’s graded hours).

Worked example

Course	Grade	Credits	Quality points
Course 1	A	3	4 × 3 = 12
Course 2	B	4	3 × 4 = 12
Course 3	C+	3	2.3 × 3 = 6.9
Course 4	A-	3	3.7 × 3 = 11.1

Total: 42 quality points ÷ 13 hours = 3.231 semester GPA. If the student already had a 3.20 GPA over 45 hours, the new cumulative GPA would be (144 + 42) ÷ (45 + 13) = 3.207.
