GPA formula
GPA = sum(grade point x credits) / sum(credits)
Each letter grade is converted to the grade point from the selected grading scale, multiplied by course credits, and divided by total credits. Grade points and rounding rules can vary by school.
Step-by-step example
- Biology: A, 3 credits = 12 quality points
- History: B, 3 credits = 9 quality points
- Total quality points = 21
- Total credits = 6
- GPA = 21 / 6 = 3.50
