Formula and weighting
GPA = Σ(grade points × credits) / Σ(credits)
Because each credit hour carries weight, a 4-credit course affects your GPA more than a 1-credit course.
This is the standard method used by most colleges and universities on a 4.0 grading scale.

FAQ
What's the standard college GPA scale?
Most institutions use a 4.0 scale, where letter grades map to grade points such as A = 4.0, B = 3.0, and F = 0.0.
How are credit hours weighted?
Each grade is multiplied by its credit hours, then the total grade points are divided by the total credits to calculate GPA.
