Frequently Asked Questions (FAQ)
What’s the formula to convert points to percentage?
The formula is: (Points Scored / Total Possible Points) × 100 = Percentage Grade. Our calculator uses this exact formula.
How do I find my overall class grade from different assignments?
To find your overall grade, you need to know the weight of each assignment (e.g., homework 20%, midterm 30%, final 50%). You cannot simply average the percentages. For this, you should use our Final Grade Calculator, which is designed to handle weighted categories.
