What this tool does
A free EZ Grader for marking papers fast. Type how many questions the test has and how many a student got wrong (or flip to number right), and you get the score percent, the letter grade, and — the part teachers actually need — a full lookup chart from 0 wrong all the way down to every answer wrong, each line showing its score and grade. Print the chart once and you grade the whole stack by counting red marks and reading across, no retyping per paper. The math is the plain shop formula: (total − wrong) ÷ total × 100, rounded to as many decimals as you choose. Letter grades use the A 90 / B 80 / C 70 / D 60 / F scale. Half-credit questions are fine — enter a decimal total like 12.5 and the chart steps in half-points. This is grading a single paper, not a course average: if you need to combine homework, quizzes and exams by weight, use a weighted or final-grade calculator instead. Everything runs in your browser, with one-click score copy and a shareable link that reopens the exact test.
