One low test does not always ruin a semester — unless it is heavily weighted. Understanding weighted averages helps you set realistic targets for remaining work.
Weighted average
Semester grade = Σ(score × weight) ÷ Σ(weights)
Example
Tests (70% weight): 62% average Homework (30% weight): 95% average Overall: 0.7 × 62 + 0.3 × 95 = 71.9%
Planning a recovery
- List remaining assignments and their weights
- Calculate the average you need on what is left
- Focus effort where points are worth the most
