What is average grade?
The grades A,B,C,D,F are given the numbers 4,3,2,1,0. Thus if
you have 4 As in one semester your Grade Point Average (GPA) for
that semester would be 4. If you had 2 As and 2 Cs your GPA would
be 3. You add up the numerical score of your grades and divide by
the number of courses. As a complication, some classes give more
"credit" than others, so that you have to give more or less weight
to the grade in the course, depending on how many credits the
course counts for. For example, a 2-credit course counts for only
half as much as a 4-credit course.
