GRADE CALCULATOR EXPLAINED

What is a grade calculator?

A grade calculator converts a raw score—such as correct answers or points earned—into a percentage score and letter grade. An easy grader can also generate a full grading chart that matches every number of wrong answers with the corresponding result.

Use it for quizzes, tests, exams, homework, rubrics, and classroom assignments. Teachers can grade answer sheets faster, while students, parents, and tutors can check a score or understand how many questions may be missed.

Point-based assignments
