At 80% going into a final worth 25%, the required score to finish at 85% is exactly 100% — achievable only with a perfect exam. The formula is (85 − 80 × 0.75) ÷ 0.25 = (85 − 60) ÷ 0.25 = 100. A final worth only a quarter of the course does not leave much room to close a 5-point gap. Adjust the numbers below to explore other scenarios.

How it's calculated
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.
