Wondering what actually is difference or relation between percentage, GPA, grade points?
GPA or Grade Point Average is calculated by taking the number of grade points a student earned in a given period of time divided by the total number of credits taken (4, here). For every subject a total of 128 clock hrs. is the time that a student must be studying the subject. SLC Board considers that a credit hour will include a total of 32 clock hours. Now, with simple mathematics, we get 4 credit hour which is the base max value for GPA as well.
For example, if a student earns a grade of “A+”, he or she would have a Grade Point Average of 3.6 out of 4 (for Excellent or Superior Performance).
