How is the overall grade calculated?

It adds up every assignment's points earned and divides by the total points possible across all assignments, giving a single weighted percentage — this matches how most courses that grade by total points (rather than by category weights) calculate a final grade.

What if my class weights categories differently (e.g. homework 20%, exams 80%)?

This calculator treats every point the same, so for weighted categories, calculate each category's percentage separately, then combine them manually using your course's weights — or enter "points possible" that already reflect each category's intended weight.

How is "points needed" for a target grade calculated?

It takes your target percentage, multiplies it by the total points possible so far, and subtracts the points you've already earned — showing how many more points (not percent) you'd need if everything stayed at the same total points possible.

Is my grade data sent anywhere?

No. All calculations run locally in your browser with JavaScript — nothing is transmitted or stored.
