公式
## How to Calculate a Weighted Average ### Formula **Weighted Average = Sum of (Score x Weight) / Sum of Weights** Weights should add up to 100%. Higher-weighted categories have more impact on your final grade.
计算示例
Homework (90%, 20%), Midterms (85%, 30%), Final (78%, 30%), Participation (95%, 20%).
- 01Homework: 90 x 0.20 = 18.0
- 02Midterms: 85 x 0.30 = 25.5
- 03Final: 78 x 0.30 = 23.4
- 04Participation: 95 x 0.20 = 19.0
- 05Total: 85.9 / 1.00 = 85.9%
