Computing Grade Point Averages

1) Grade points are computed on the basis of four points for each credit of A, three points for each credit of B, two points for each credit of C, one point for each credit of D, and zero points for each credit of F.
2) Grades of P and NP and marks of, I, W, and AUD are disregarded in the computation of the grade point average.
3) The grade point average is the quotient of the total points divided by the total credits in which A, B, C, D, and F are received.
