1. What is a Weighted Grade?

Unlike unweighted grading where every assignment carries equal points, weighted grading assigns different percentage weights to different categories of coursework. For instance, a final exam might account for 40% of your total grade, while weekly homework accounts for 20%.

2. The Weighted Grade Formula

Weighted Final Grade (%) = Σ (Category Score % × Category Weight %) / Σ (Category Weights %)
