How the EZ Grader Works
This is the classic teacher’s grading tool: enter how many questions are on the test and how many the student got wrong, and it instantly gives the percentage and letter grade. The score is the number correct divided by the total, times 100 — and because it’s the same for every paper, you can grade a whole stack fast just by counting the marks wrong.
The letter grade uses the standard US scale (90+ is an A, 80s a B, and so on). It works for any number of questions, so it handles quizzes of 7 or exams of 100 equally well.
score = (questions − wrong) ÷ questions × 100
