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.
How is this different from the Grade Calculator?
This page converts one points total. The Grade Calculator lets you add multiple assignments and total them automatically.
