Frequently Asked Questions

How do I calculate what I need on my final?

Multiply your current grade by (1 − final weight), subtract that from your target grade, then divide by the final weight. This calculator does it instantly.

What if my final is worth 0%?

Then the final cannot change your course grade — your grade is already determined by the graded work so far.

What if the required score is above 100%?

It means the target is mathematically unreachable without extra credit or a grading curve. Try a slightly lower target to see what is achievable.

Does this work for weighted categories?

Yes — if you know your current overall grade and the final's weight, the category breakdown does not matter for this calculation.
