How it works
The easy grader table works backward from a fixed total: for each possible number of wrong answers, it shows the resulting number correct, the percentage score, and the matching letter grade on a standard U.S. grading scale. It's built for teachers grading by hand who want to look up a score at a glance instead of doing the division each time.
