How it works

Grade = Σ(score × weight) ÷ Σ(weight)

Frequently Asked Questions

Do the weights need to add up to 100?
No. The weights can be any numbers; they are divided by their own total, so 20/30/50 and 2/3/5 give the same result.
Can I use fewer than five rows?
Yes. Only rows with a weight are counted, so leave the rest blank.
