About EZGradeHub

EZGradeHub is a free online grade calculator built for students checking their scores and teachers grading tests, quizzes, exams and assignments. You enter the total number of questions and the number of wrong answers, and the tool works out the correct count, the percentage score and the matching letter grade.

The calculation follows a simple formula: subtract wrong answers from total questions, divide by the total, and multiply by 100. A grading scale on the page shows which letter grade each percentage range maps to, and a short guide explains the steps with worked examples. The site also lists related calculators for final grades, GPA and cumulative GPA.

No account or sign-up is needed to use the calculator, and the site says the calculation runs in the browser without requiring personal information. Because the letter grades follow the scale shown on the site, your school may use different cutoffs.
