Frequently asked questions
How is a weighted grade calculated?
Multiply each score by its weight, add them up, and divide by the total weight. This tool does it and shows your letter grade.
What if my weights don't total 100%?
The calculator still divides by the total weight you entered and flags when it isn't 100%, so you can spot a missing category.
