How it is calculated
Weighted average = Σ (mark × weight) ÷ Σ weights Needed on remaining = (target × total weight − Σ done) ÷ remaining weightWeights can be percentages (summing to 100) or coefficients (2, 3…) — the result is the same.
Worked example
Quiz 1: 14/20 (weight 1), quiz 2: 12/20 (1), exam: 15/20 (2): average = (14 + 12 + 30) ÷ 4 = 14.
Frequently asked questions
Simple vs weighted average?
A simple average weighs every mark equally; a weighted one gives important components more weight.

Yes — enter each subject with its coefficient and average.
What does “needed on remaining” mean?
