My grade is at a 77% and I want an 80%. I have my exam worth 20% what would my grade be if I scored a 85%

Answer 1

To calculate your new grade, you need to consider the weightage of your exam and the current grade.

Given:
Current grade = 77%
Exam worth = 20%
Exam score = 85%

First, calculate the portion of the grade that comes from the exam:
Exam portion = (Exam score) x (Exam weight) = 85% x 20% = 17%

Next, calculate the remaining grade before the exam:
Remaining grade = 100% - Exam weight = 100% - 20% = 80%

Now, add the grade from the exam portion to the remaining grade:
New grade = Remaining grade + Exam portion = 80% + 17% = 97%

Therefore, if you score 85% on your exam, your new grade overall would be 97%.
