Frequently Asked Questions
What is a weighted average?
A weighted average gives more importance to some grades than others. A final exam worth 40% affects your grade more than a quiz worth 5%, even if you scored the same on both.
How do I convert percentage to letter grade?
A: 90-100%, B: 80-89%, C: 70-79%, D: 60-69%, F: below 60%. Some schools use +/- grades (A+, A, A-).
