The grade earned so far on everything except the final.
One percentage per graded category, e.g. "92, 85, 78".
The weight of each category, in the same order, e.g. "30, 30, 20".
Raise above 100 if the final offers extra credit.

A-
Worked out from Weighted-mean course grade identity: target = current x (1 - w) + final x w, solved for the final score and 4 other sources.

How this is worked out

4 steps
  1. Grade banked so far = 88% over 80% of the course
  2. Course grade = 88 x 0.8 + final x 0.2
  3. Setting that equal to 90%: final = (90 - 70.4) / 0.2 = 98%
  4. Scoring 100% gives 90.4%; scoring 0 gives 70.4%.
