How Grade Calculation Works

- Letter grades are converted to grade points and percentages (see table below).
- Multiply each grade's percentage by its weight, sum, and divide by total weight to get your weighted average.

Example Calculation
- Homework (A, 20%): 95 x 20 = 1900
- Midterm (B+, 30%): 88 x 30 = 2640
- Final Exam (A-, 50%): 91 x 50 = 4550
- Total weight: 100
- Total weighted score: 1900 + 2640 + 4550 = 9090
- Weighted average = 9090 / 100 = 90.9% (A-)
