Final exam 成绩 calculation.
The final exam 成绩 is equal to 100% times the required grade, minus 100% minus the final exam 重量 (w) times the current grade (g), divided by the final exam weight (w):
Final exam 成绩 =
= ( 100%×required 成绩 - (100% - w)×current 成绩 ) / w
Current 成绩 is 70% (or C-).
Final exam 重量 is 50%.
Required 成绩 is 80% (or B-).
The final exam 成绩 is equal to 100% times the required grade, minus 100% minus the final exam 重量 (w) times the current grade (g), divided by the final exam weight (w):
Final exam 成绩 =
= ( 100%×required 成绩 - (100% - w)×current 成绩 ) / w
= ( 100%×80% - (100% - 50%)×70% ) / 50% = 90%
So the final exam 成绩 should be 90% (or A-).
