How your UIUC 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).

Repeated courses

Illinois has separate rules for repeated courses. This calculator counts every attempt you enter. Check with the Office of the Registrar for how a specific retake will be handled.

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	2.33 × 3 = 6.99
Course 4	A	3	4 × 3 = 12

Total: 42.99 quality points ÷ 13 hours = 3.307 semester GPA. If the student already had a 3.20 GPA over 45 hours, the new cumulative GPA would be (144 + 42.99) ÷ (45 + 13) = 3.224.
