## How Weighted Grades Work
Weighted grading assigns different importance to categories. A final exam worth 40% affects your grade more than homework worth 30%.
### Formula
**Weighted Grade = (Score_1 x Weight_1 + Score_2 x Weight_2 + ...) / Total Weight**
Each category's contribution equals its score times its weight divided by total weight. This ensures proper proportional representation.

Exemplo Resolvido
Homework: 88% (30% weight), Midterm: 76% (30% weight), Final: 82% (40% weight).
- HW contribution: 88 x 30 = 2640
- Midterm contribution: 76 x 30 = 2280
- Final contribution: 82 x 40 = 3280
- Total: 2640 + 2280 + 3280 = 8200
- Weighted grade: 8200 / 100 = 82.0%
