Before you rely on the number
Things worth checking
- Use the real point values rather than the question count when questions are worth different amounts.
- Percentages above 100% are legitimate when extra credit pushes points earned past points possible.
- Converting several assignments at once is faster in the grade calculator, which totals the rows for you.
Common questions
Percentage Grade Calculator FAQ
Can a percentage be over 100%?
Yes, if extra credit makes points earned greater than points possible.
What if the assignment has weighted questions?
Add the actual points earned and possible across all questions rather than using the question count.
