## How to Calculate Cumulative GPA

Cumulative GPA combines all semesters into a single weighted average.

### Formula

**Cumulative GPA = (Previous Quality Points + New Quality Points) / Total Credits**

Where:
- Previous Quality Points = Previous GPA x Previous Credits
- New Quality Points = Semester GPA x Semester Credits

计算示例

A student has a 3.2 GPA over 60 credits and earns a 3.5 GPA in a 15-credit semester.

  1. Previous quality points: 3.2 x 60 = 192.0
  2. New quality points: 3.5 x 15 = 52.5
  3. Total quality points: 192.0 + 52.5 = 244.5
  4. Total credits: 60 + 15 = 75
  5. Cumulative GPA = 244.5 / 75 = 3.26
