Grade a stack
How to use the easy grader
- Enter the number of questions. Type it, use the + and − buttons, or tap one of the common sizes. The grading chart updates straight away.
- Find the score. Read it off the chart, or type how many the student got wrong into Number wrong to see the percentage, the letter grade and how many more right answers the next grade needs.
- Print it if you like. Print chart fits the whole chart on one page, sized as large as it will go — handy to keep in your grading folder or clip to a clipboard.
It is free, there is nothing to sign up for, and it works on a phone, a tablet or a computer.
Grading a whole stack of papers
When you have thirty tests to mark, use Grade a stack. Type the number wrong on the first paper and press Enter (or tap Add to stack). The box clears itself, ready for the next paper. As you go, the side panel keeps a running count, the class average and median, and how many students landed on each grade — a quick check on whether the test was too hard before the scores go in your gradebook.
When you are done, Copy puts every score on the clipboard with a header row, so it pastes straight into Excel or Google Sheets. Tapped the wrong number? Use Undo, or click any score in the list to remove it.
Student privacy: the stack never asks for names, and the scores are saved only in your own browser. Nothing is sent to us or anyone else.
How the percentage is worked out
A grade percentage is the number right divided by the number of questions, times 100:
(questions − number wrong) ÷ questions × 100
For a 25-question quiz with 3 wrong: (25 − 3) ÷ 25 × 100 = 88%. The same works for points: switch Grading by to Points in the settings and enter the total points and the points lost. If you give half marks, tick Allow half marks and the chart adds a row for every half point.
Grading scales
Schools use different scales, so the easy grader lets you pick one or type in your own. The three most common in the US:
| Grade | 10-point scale | 7-point scale | Plus / minus scale |
|---|---|---|---|
| A | 90–100% | 93–100% | A 93+, A− 90–92 |
| B | 80–89% | 85–92% | B+ 87–89, B 83–86, B− 80–82 |
| C | 70–79% | 77–84% | C+ 77–79, C 73–76, C− 70–72 |
| D | 60–69% | 70–76% | D+ 67–69, D 63–66, D− 60–62 |
| F | below 60% | below 70% | below 60% |
If your district uses something else, open Settings and change the lowest percent for any grade. Copy link saves your scale in the link, so you can bookmark it and it opens the same way every time.
Does 89.5% round up to an A?
On most school scales, yes — a score is rounded to a whole percent first, so 89.5% becomes 90% and earns an A. That is what the easy grader does by default, so the chart never shows a confusing “90% B”. If your school grades the exact score with no rounding up, tick Grade the exact score in the settings and 89.5% stays a B. You can also show scores to one or two decimal places.
Tips for faster grading
- Mark wrong answers, not right ones. On most tests there are fewer, so counting them is quicker — that is why the chart lists the number wrong. Prefer counting correct answers? Switch Chart lists to Number right.
- Use the keyboard. The arrow keys change the number wrong, and Enter adds the paper to the stack, so you never need the mouse.
- Print one chart per test length. If you give the same 10- and 20-question quizzes every week, print both and keep them with your answer keys.
- Look at the spread, not just the average. If most of the class landed on a D, the test may have covered something that needs reteaching.
