Example: GPA Calculation
Let’s say you completed the following three classes:
| Course | Grade | Credit Hours |
|---|---|---|
| Math | A | 3 |
| English | B+ | 4 |
| Chemistry | C | 3 |
Step 1: Convert Grades
- A = 4.0
- B+ = 3.3
- C = 2.0
Step 2: Multiply by Credit Hours
- Math: 4.0 × 3 = 12.0
- English: 3.3 × 4 = 13.2
- Chemistry: 2.0 × 3 = 6.0
Step 3: Total Grade Points & Credits
- Total Grade Points = 31.2
- Total Credit Hours = 10
Step 4: Final GPA
GPA = 31.2 ÷ 10 = 3.12
