How it works

Σ(score × weight) ÷ Σweight

Each score counts in proportion to its weight. Homework at 20%, midterm at 30% and the final at 50%: multiply each score by its weight, add them, and divide by the total weight. Without weights, every score counts the same. The letter uses the common US scale (A 90+, B 80–89, C 70–79, D 60–69, F below 60); your school may use another.

  1. Weighted sum of the scores Σ(score × weight) ÷ Σweight = 82.9%
