I think “quality points” are just how the figure GPA
Each hour of A, B, C, D and F carries a grade point value as follows: A=4, B=3, C=2, D=1 and F=0. Grades of P and S, as well as grades of I, X, U, N, NP, AW, and W, carry no grade point value and are not included in the computation of a student’s semester or cumulative grade point average.
Total quality points divided by the number of credit hours gives the GPA on a four point scale.
