How the Easy Grader (EZ Grader) Works for Teachers
The Easy Grader (traditionally known in American classrooms as an EZ-Grader) is an essential scoring lookup chart that displays the exact percentage score and corresponding letter grade for every possible number of wrong answers on any test or quiz.
Instead of manually calculating $(N - \text{wrong}) / N \times 100$ for 30 individual test papers with a handheld calculator, an EZ Grader chart allows an instructor to glance down a printed column to instantly find the grade in under 2 seconds per paper.

Frequently Asked Questions
How do I print a clean grading chart for my physical gradebook?
Click the "Print Grading Chart" button at the top of the grid. Our custom print styling isolates only the table, hiding all website menus and advertisements so it prints cleanly across 1 or 2 columns on a single A4 page.
Does the calculator support half-point deductions?
Yes! Check the "Include half points (0.5 increments)" box under filter options to see precise half-point penalties (e.g. 0.5 wrong, 1.5 wrong, 2.5 wrong).
