## Overview

At 65% with 40% of the course riding on the final, you need 77.5% on that exam to finish exactly at 70%. The math: (70 − 65 × 0.60) ÷ 0.40 = (70 − 39) ÷ 0.40 = 77.5. With a final worth nearly half the course, there is real room to move — a perfect final would bring you to 79%. Enter your own numbers below.

## Method

The required final score is derived from the weighted-average course grade formula: course grade = current × (1 − w) + final × w, where w = finalWeight / 100. Rearranging to isolate the final exam score gives: required = (target − current × (1 − w)) / w. The best-case course grade assumes a perfect 100 on the final; the worst-case assumes 0. Both are computed from the same formula with the final score substituted in.
