EZ Grader
A digital EZ grader that replaces the classic slide chart teachers have used for decades. Type the number of questions on the test or quiz, and instantly get the full grading table — every possible number of wrong answers with its percentage score and letter grade. Tap a common test size to fill it even faster, and grade a whole stack of papers in minutes.
How the EZ grader works
Score = (correct answers ÷ total questions) × 100. The table lists every outcome for your test length so you can mark papers without touching a calculator. Letter grades follow the standard US scale; if your school uses a different cut-off (like 70% = C), the percentage column still gives you everything you need.
Frequently asked questions
Can I use it for quizzes with half-point questions? Yes — double everything. A 15-question quiz with half points is a 30-point quiz.
