How the weighted grade is calculated
Multiply each grade by its weight, add the results, then divide by the total weight: (grade1 × weight1 + grade2 × weight2 + ...) ÷ total weight
Example: 90% on homework (20% weight) and 80% on a midterm (30% weight) gives (90 × 20 + 80 × 30) ÷ 50 = 84%.
Do weights have to add up to 100?
No. If they add up to less than 100, the result shows your grade on the work counted so far, and the target section tells you what you need on the remaining weight.
