The Easiest Online Grader for Teachers
Grading a stack of papers should not require a calculator app, a spreadsheet, or a paper EZ-grader wheel. QuickGrade is a completely free ez grader and easy grader that helps you quickly calculate the percentage score for assignments, quizzes, and tests. By simply entering the total number of questions and the number of wrong answers, you get instant results — no manual calculation, no extra steps.
The ez grader calculator is built for teachers who grade stacks of assignments quizzes and tests every week. Entering the total number of questions takes a second, and from there each wrong answer updates the score in real time. The grade calculations follow a standard percentage score model, so the output works with any grading scale your school uses.
QuickGrade removes the slow part of grading. You no longer need to repeat the same grade calculations on a calculator for every paper. Just set the questions and wrong answers, watch the percentage score appear, and move on to the next student. Because the tool is completely free and runs in any browser, you can use it on a phone between classes or on a laptop at your desk.
