Question: how to calculate grade by percentage weight?
Answer: Weighted grade = (93×10%+ 85×20%+ 86×20%+87×25%)/(10%+ 20%+ 20%+ 25%) = 87 percent. To get an overall grade of 88 percent, the final grade need to be: (88×100%- 87×75%)/25% = 91 percent. Tip: you can adjust your overall grade to calculate the corresponding final grade in real time.
