计算 final exam 成绩 from current grade and the target grade:
计算 final exam 成绩 from multiple current grades and target grade:
计算 total class 成绩 from current grade and final exam grade:
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 the required grade, minus 100% minus the final exam 重量 (wfinal) times the current 成绩 (g), divided by the final exam 重量 (w):
Final exam 成绩 =
So the final exam 成绩 should be 90% (or A-).
Assigment 1: weight1=50%, grade1=16 out of 20.
Assigment 2: weight2=30%, max 成绩=30.
Assigment 3: weight3=20%, max 成绩=40.
Find average 成绩 in assignments 2 and 3 needed to get class grade of 85%.
Current 成绩 = Assignment 1 grade = grade1 / max grade1 =
= 16/20 = 0.8 = 80%
Required 成绩 = 85%
Final exam 重量 = w = weight2+weight3 = 30%+20% = 50%
Final exam 成绩 =
This mean that you have to get an average 成绩 of 90% in assignments 2 and 3 in order to get class grade of 85%.
Assignment 2 成绩 = 90% × max 成绩 = 90% × 30 = 27
Assignment 3 成绩 = 90% × max 成绩 = 90% × 40 = 36
