figure out what your grades are in each class. then take the number of credit hours each class is & multiply it by the number above (if you got an A in a 4 credit hour class then that is 16). add all the numbers up & divide by the number of credit hours you took.
example B+ - 5 credit course; D - 2 credit course; C - 3 credit course = C+
