Needed = (target − current×(1−w)) ÷ w, where w is the final's weight. Example: 82% average, 30% final, targeting 90% → (90 − 57.4) ÷ 0.30 = 108.7% — impossible; targeting 87% needs 98.7%. The calculator solves your exact numbers.
If 1 of 10 quizzes drops, your quiz average uses the best 9 — enter only counted scores, or average all 10 and note the tool assumes equal weights within the category unless specified.
Weighted: categories have % weights (exams 40%, homework 30%...). Points-based: total points earned ÷ total possible. This tool uses weights — for points systems, convert: each assignment's weight = its points ÷ course total.
Math, not hope: +3% extra credit on a 10%-weighted category adds 0.3% overall. Enter it as a bonus category with its weight to see the true (usually small) effect.
