How Semester, Cumulative, and Program GPA Are Calculated
Purdue's semester grade point average is the sum of index points (grade weight × credit hours) earned in a term, divided by the total graded semester hours. Cumulative and program GPAs are computed the same way, using the same weighted grades (University Senate Document 7-5, April 21, 2008).
