Easy Grader
Give the number of questions and how many were missed to get the percentage grade, letter, and a quick chart.
How it works
This is the digital version of the grading wheel taped to a teacher's desk. Instead of counting up correct answers, you count the misses — usually the smaller, faster number — and it works out the rest.
Enter how many questions the set had and how many were wrong. On a 20-question quiz, 3 wrong leaves 17 right, which is 85% and a solid B. Change either number and the grade updates the instant you type it.
Below the result it lays out a small chart for that question count: zero wrong, one wrong, two wrong, and so on, each with its percentage. Grade a stack of papers straight down the chart without re-entering anything.
Frequently asked questions
Why enter wrong answers instead of correct ones?
On most graded sets the misses are the smaller number, so it's quicker to count and less error-prone. The tool subtracts them from the total for you and grades what's left.
What's the grading chart for?
It's a ready-made lookup for the question count you entered — every possible number of misses paired with its percentage. When you're marking a pile of the same quiz, you glance at the chart instead of recalculating each one.
What happens if I say more wrong than there are questions?
The count is capped at the total, so you can't drop below zero correct. Worst case it reads as a 0%, which is exactly what an all-wrong paper should score.
