Final grade calculation

Example #1

current grade is 70% (or c-).

final exam weight is 50%.

required grade is 80% (or b-).

Calculation:

384彩的新版网站the final exam grade is equal to the required grade, minus 100% minus the final exam weight (w) times the current grade (g), divided by the final exam weight (w):

final exam grade =

= ( required grade - (100% - wcurrent grade ) / w

= ( 80% - (100% - 50%)×70% ) / 50% = 90%

so the final exam grade should be 90% (or a-).

Example #2

assigment 1: weight1=50%, grade1=16 out of 20.

assigment 2: weight2=30%, max grade=30.

assigment 3: weight3=20%, max grade=40.

find average grade in assignments 2 and 3 needed to get class grade of 85%.

Calculation:

384彩的新版网站current grade = assignment 1 grade = grade1 / max grade1 = 16/20 = 0.8 = 80%

required grade = 85%

Final exam weight = w = weight2+weight3 = 30%+20% = 50%

final exam grade =

= ( required grade - (100% - wcurrent grade ) / w

384彩的新版网站= ( 85% - 50%×80% ) / 50% = 90%

this mean that you have to get an average grade of 90% in assignments 2 and 3 in order to get class grade of 85%.

Assignment 2 grade = 90% × max grade = 90% × 30 = 27

Assignment 3 grade = 90% × max grade = 90% × 40 = 36
