Easy Grader
Grade a test in seconds. Enter the total number of questions and how many the student got wrong to get the percentage, letter grade and a full score chart for every number wrong.
Grade a stack of papers fast
When you have thirty papers to mark, doing the percentage in your head for every possible number wrong slows you down. This easy grader works like the classic teacher's grading wheel: set the number of questions once, and it gives you the percentage for any number a student got wrong, plus a full chart you can glance at while you grade.
How to use it
Enter the total number of questions on the test. Then type how many a particular student got wrong to see their exact percentage and letter grade. The score chart below shows the grade for every number wrong from zero upward, so for a whole class you can simply look down the list instead of recalculating each time.
Beyond simple tests
The easy grader is perfect for quizzes and tests where every question is worth the same. For assessments with weighted sections or categories, use our Weighted Grade Calculator. To curve a whole set of results, the Grade Curve Calculator will help.
