How it works
A weighted average multiplies each value by its weight (coefficient), adds those products, then divides by the total of the weights. It's the standard way schools compute a term average when subjects don't count equally.

Frequently asked questions
How is a weighted average calculated?
Multiply each grade by its coefficient, add the results, then divide by the sum of the coefficients.
What if all weights are equal?
Then the weighted average equals the simple average (the plain mean of your values).
