How the weighted average works

Each assignment or category you enter contributes to your final grade in proportion to the weight you assign it — a 30%-weighted final exam counts three times as much as a 10%-weighted quiz, regardless of how many points each was scored out of. The calculator normalizes your weights internally, so it still returns a sensible average even if the weights you've entered don't add up to exactly 100%.

Frequently asked questions

We multiply each assignment’s score by its weight, add those up, then divide by the total weight you’ve entered. This is the standard weighted-average method most instructors use.

That’s fine — the calculator normalizes against whatever total weight you’ve entered, so partial grading schemes still work correctly.
