Instructors in undergraduate and graduate courses use a grading system that includes plus and minus grades as well as straight grades for all undergraduate and graduate course records. The registrar computes numerical grades for plus and minus grades when calculating grade point averages (GPAs) (A+ or 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, D–=0.7, F=0.0). A minimum cumulative grade point average of 2.0 is required for graduation.

Credit points are calculated by multiplying the grade points earned in a course by the number of credit hours for that course. For example, 3 hours of A=12 grade points. The grade point average for a semester is computed by dividing the total number of credit points earned by the number of credit hours attempted.

Suppose that a student has earned the following grades in a semester:

3 credit hours of A (12 credit points)

3 credit hours of B (equals 9 credit points)

3 credit hours of C+ (equals 6.9 credit points)

3 credit hours of D- (equals 2.1 credit points)

3 credit hours of F (equals 0 credit points)

The semester grade point average would be 2.0 (30 credit points divided by 15 credit hours) 

GPAs are calculated on a 4.00-point scale based on the highest grade a student achieves in a course. In cases of a student retaking a course that is not repeatable for credit, the highest grade of all attempts will factor into the GPA. Extended-X and program-level rules about repeats and failed grades are still in effect.
