How to calculate the grade needed on the final
Required final score = (target grade − current grade × (1 − final weight)) ÷ final weight.
With an 82% current grade, an 85% target, and a final worth 30%: (85 − 82 × 0.70) ÷ 0.30 = 92%. If you expect 80% on the final, the predicted course grade is 82 × 0.70 + 80 × 0.30 = 81.4%.
Use the weight as a decimal: 30% = 0.30. This formula assumes the current grade summarizes all completed work and the final covers the remaining weight; check your course rules for minimum scores, rounding, curves, dropped work, or extra credit.
