A, A−, B+ and so on, or a grade point such as 3.7.

With the grade points for each course.
How GPA is calculated
Each letter grade has a point value: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0. Multiply each course’s points by its credits, add them up, and divide by the total credits. Courses with more credits count more.
GPA formulas
Grade points for a course = grade value × credits
GPA = total grade points ÷ total credits
Cumulative GPA = (old GPA × old credits + new points) ÷ all credits
Example 1: one semester
Math A (3 credits), English B+ (3), Biology A− (4), History B (3).
- Grade points 12.0 + 9.9 + 14.8 + 9.0 = 45.7
- Credits 13
- Semester GPA 3.52
Example 2: cumulative GPA
A 3.2 GPA over 45 credits, plus the semester above.
- New cumulative GPA 3.27 over 58 credits
The 4.0 grade scale
