The easy grader that does more than divide
Every teacher knows the grading wheel: spin it to the number of questions, and it tells you the score for each number wrong. This is that tool, without the cardboard — and without the ads and pop-ups the other online versions bury it under. Enter your question count, and the full chart appears instantly. Grade a whole class by reading across a row.
But a chart only tells you one score at a time, and then forgets it. The reason teachers keep a gradebook is that a mark isn't finished when you calculate it — it has to be recorded, weighted against everything else, averaged, and eventually shared with the student and put on a report. That's the part that actually eats your evening.
From a number to a real grade
Inside Level Up Classroom, the score you just calculated becomes a permanent mark: filed under the right category, weighted the way your course grades, folded into a live average, and visible to the student the moment you release it. You enter it once. No spreadsheet, no re-typing, no end-of-term arithmetic. It's free to start, with a full weighted gradebook on the free plan.
Run your whole classroom from one tab
That number you just worked out lives nowhere. In Level Up Classroom the same calculation lands in a weighted gradebook, against the right student, in the right category — and turns into a report card comment at the end of term. Free plan, no credit card.

Easy grader FAQ
How do I calculate a test grade by number wrong?
Enter the total number of questions on the test. The chart shows each number of wrong answers mapped to a percentage and letter grade. To grade a paper, find the number wrong and read across — on a 20-question test, 3 wrong is 17/20, or 85%.
What's the grade if 5 out of 20 are wrong?
5 wrong out of 20 means 15 correct: 15/20 = 75%, a C on a standard scale. Enter 20 questions above and tap the "5 wrong" row to see it.
How does an EZ grader / easy grader work?
It's a lookup tool: tell it how many questions are on the assignment and it precalculates the score for every possible number of wrong answers, so you're not dividing over and over while marking a stack.
Can I set my own grade cutoffs or plus/minus scale?
This grader uses a standard A/B/C/D/F scale (90/80/70/60) by default, and you can turn letter grades off if your school reports percentages only. The percentage for each number wrong is always exact.
How do I convert points earned to a percentage and letter grade?
Divide points earned by points possible and multiply by 100 — 42 out of 50 is 84%. Switch to "By points" mode above to enter points earned and possible directly.
