Question: how to calculate grade using weighted percentages?
Answer: Then using a calculator the overall grade is calculated as: Overall grade = (93×10%+ 85×20%+ 86×20%+87×25%+ 91×25%)/100% = 88 percent. In the scenario of before final exam, the average grade is: Weighted grade = (93×10%+ 85×20%+ 86×20%+87×25%)/(10%+ 20%+ 20%+ 25%) = 87 percent.
