Rework your gpa using them instead. Multiply the credits by the grade points, sum them and then divide by the total number of credits.
Not sure that will work since there are more letter grades for his system than our system. I suggest this. With Ex, A, B, C, D, P, F, there 6 gaps between the letters.
