Grading a big stack of test papers takes a lot of time. You have to divide numbers, do math, and figure out the letter grade for each student. This is slow and easy to get wrong.
That's why teachers use an easy grader. It does all the math for you in less than a second. In this article, we'll explain what an easy grader is, how it works, and how you can use EasyGrader.org — the best free easy grader online — to save time every single day.
What Is an Easy Grader?
An easy grader is a tool that helps teachers quickly find out a student's score and letter grade. You enter two things:
- How many questions were on the test
- How many answers were wrong
The easy grader then gives you the percentage score and the letter grade (like A, B, C, D, or F) right away. No math needed from you.
In the old days, teachers used a small plastic or paper wheel called an easy grader. Today, you can use a free online easy grader like EasyGrader.org — and it works much faster.
How Does It Work?
The easy grader uses a very simple formula:
Here's a simple example: A student answers a 20-question test and gets 4 questions wrong.
- Correct answers = 20 − 4 = 16
- Score = (16 ÷ 20) × 100 = 80%
- Letter grade = B
The easy grader does this math for every student in your class — instantly.
Example Results for a 40-Question Test
| Wrong Answers | Score % | Letter Grade |
|---|---|---|
| 0 | 100% | A |
| 4 | 90% | A |
| 6 | 85% | B |
| 10 | 75% | C |
| 14 | 65% | D |
| 17 | 57% | F |

- Use custom scale. If your school uses different grade cutoffs, use the Custom Scale tab so results are always correct.
- Grade question by question. Mark all papers on question 1 first, then question 2, and so on. This is faster and more consistent.
- Share grades easily. Use the Share button to send a student's result to their parents in one click.
- Try dark mode. If you grade at night, turn on dark mode to reduce eye strain.
