How do I grade a test quickly?

Enter total questions and wrong answers. The EZ grader shows the percentage and letter grade immediately, plus a full chart for every wrong-count.

Can teachers use this as an easy grader?

Yes. Teachers use it to score quizzes in seconds without login. Print the grading chart for your desk.

We default to the common US 4.0 GPA scale. Your region may be detected automatically, or you can pick a different scale in the calculator settings.

Grade tests quickly by number of questions and wrong answers.

Score % = (Correct ÷ Total) × 100

Example: A 10-question quiz with 2 wrong answers: 8 correct → 80% → typically a B− on the US scale. Letter cut-offs use the unrounded result.
