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 79%?
To calculate your grade after the exam, you need to consider the weightage of each component. Since your exam is worth 20% and your current grade is 77%, you can calculate the contribution of the exam as follows:
Exam contribution = (Exam score) * (Exam weightage)
= 79% * 20%
= 0.79 * 0.20
= 0.158
Now, to calculate your overall grade, you need to add this contribution to your current grade:
Overall grade = Current grade + Exam contribution
= 77% + 0.158
= 77.158%
So, if you scored a 79% on your exam, your overall grade would be approximately 77.158%.
