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.
