How it is worked out
- Grade points on the common 4.0 scale: A 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0.
- GPA = total quality points ÷ total credits = 49.2 ÷ 15 = 3.28. Your school may use a different scale (for example A+ = 4.3 or weighted honours courses).
| Inputs | Answer |
|---|---|
| One course per line: grade then credits: A 3 B+ 4 A- 3 B 2 C+ 3 | The GPA for 5 courses and 15 credits is 3.28 on a 4.0 scale. |
| One course per line: grade then credits: A 4 A 3 A- 3 | The GPA for 3 courses and 10 credits is 3.91 on a 4.0 scale. |
| One course per line: grade then credits: B 3 B- 3 C 4 D+ 2 | The GPA for 4 courses and 12 credits is 2.31 on a 4.0 scale. |
How to use it
GPA is total quality points divided by total credits. Each course earns its credits times the grade points of its letter: A 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0. A 3-credit A gives 12 points.
This is the common 4.0 scale. Your school may use another scale (for example A+ = 4.3) or weight honours and AP courses, so check your registrar's rules for official figures.
