What if the required score is over 100%?

That means the target isn't reachable with this final alone. The tool shows the maximum grade you can still achieve.

What if it says I need 0%?

You've already secured your target — even a zero on the final keeps you at or above it.

Does this work for weighted categories or just the final?

It models your current grade as everything-but-the-final. Combine categories into one 'current grade' first, then set the final's weight.

How it works

Your current grade counts for the rest of the course; the final counts for its weight. Required final = (desired − current × (1 − weight)) ÷ weight. If the number is above 100 the target isn't reachable; if it's at or below 0 you've already secured it.

Private by design. This tool runs entirely in your browser — nothing you enter is uploaded or stored, and it works offline.

About

The tool uses the standard weighted-grade formula: required final = (target − current × (1 − weight)) ÷ weight, where weight is the final exam's share of the course. It interprets the result for you — telling you if you've already secured the target (a 0 would still pass), if the target is mathematically impossible even with a perfect score, or exactly what percentage you need. It also shows the best and worst overall grade you can still earn given your current standing.

How to use

Enter your current grade as a percentage (e.g. 82).
Enter how much the final exam is worth, as a percentage of the course (e.g. 30).
Enter the overall grade you want. The required final score appears instantly.
