Your figures

Updates as you type
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.
Letter:minimum percent pairs used for the "what each letter needs" table.

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%.

The 10-point scale (A 90-100, B 80-89, C 70-79, D 60-69, F below 60) is the dominant US convention; the 7-point scale (A 93-100, B 85-92, C 77-84, D 70-76, F below 70) is used by a minority of districts. Both are published district policy rather than a national standard, so the engine lets the user edit the cut-offs.
