Teacher Tools
Two tools for marking a stack of papers quickly: a grader that scores as you type, and a printable chart covering every possible score on a test.
Both work in whole questions of equal value, both let you set your own grading scale, and both print cleanly without the site around them.

Grade Chart
Generate and print a full grading chart for any number of questions, with thresholds you control.
Which one should I use?
- Easy Grader — set the question count once, then type how many each student got wrong. Fastest when you are working through papers one at a time.
- Grade Chart — generate the whole table, mark your passing score, and print it. Fastest when you would rather read scores off a sheet than type at all.
They share the same arithmetic, so a printed chart and a typed score will never disagree.
How the scoring works
Every question is worth the same share of the test. Subtract the wrong answers from the total, divide by the total.
On a 20-question test each question is worth 5%, so three wrong is 85%. On a 30-question test each is worth 3.33%, and the same three wrong is 90%.
Test length changes everything
How finely you can grade is decided entirely by how many questions you set. This is worth knowing when writing a quiz, not just when marking one:
| Questions | Each is worth | One wrong | Scores available near 70% |
|---|---|---|---|
| 5 | 20% | 80% | 80%, 60% |
| 10 | 10% | 90% | 80%, 70%, 60% |
| 20 | 5% | 95% | 75%, 70%, 65% |
| 25 | 4% | 96% | 72%, 68% |
A five-question quiz has no score between 80% and 60%, so a pass mark of 70% behaves identically to one of 65%. Twenty, twenty-five and fifty questions are common choices because they divide neatly into the usual grade boundaries.
Important notes
Grade boundaries are yours to set
The percentages these tools produce are fixed arithmetic. The letter beside them depends on where your school sets its cut-offs, which vary widely. Switch the grading scale before printing a chart you intend to rely on.
- Equal-weight questions only. For part marks or a long-answer question worth ten points, use the Grade Calculator and work in points.
- Up to 200 questions. Beyond that a chart is no longer something you can read on paper.
- Curves and dropped questions are applied afterwards and are not modelled here.
