How the grader works
The slider works like the cardboard grading slides many teachers keep in a drawer, only it fits any test and prints a clean table. Grading a stack of tests is faster when you do not calculate every percentage by hand. This tool does the math once and shows you the result for every possible score. You only choose three things: how many points the test is worth, which grading scale you use, and whether half points exist.
- Enter the total. Use the number of questions or the maximum points, for example 25 or 37.5.
- Pick a scale. Start with the classic A–F scale or switch to plus and minus grades. Need different cutoffs? Choose Custom and type your own.
- Move the slider. The highlighted row glides to the matching score. The big grade badge, the percentage and the points update as you move.
The table under the slider lists all scores from perfect down to zero. Select any row to jump to it, copy the table into a spreadsheet, or print it and pin it next to your pile of tests.
A worked example
Take a quiz with 25 questions on the standard A–F scale. An A starts at 90%, so you need at least 22.5 points. Without half points that means 23 correct answers, or at most 2 wrong. A B starts at 80%: 20 correct answers, 5 wrong at most. A C needs 70%, which is 17.5 and therefore 18 correct, and a D needs 60%, which is exactly 15.
The cutoff cards show this at a glance, so you can decide before you start grading. With half points turned on, the A line moves to 22.5 points and the C line to 17.5 points, because a half point is allowed to count.
Choosing a grading scale
There is no single official grading scale in the United States. Many schools use the 10-point scale (A at 90% and up, B at 80%, C at 70%, D at 60%), many add plus and minus grades, and some districts use a 7-point scale. The presets here are common defaults. If your syllabus says otherwise, the Custom option lets you name your grades and set each starting percentage. Your settings are kept in the page URL, so you can bookmark or send a link to a colleague.
You can also see all scales side by side in the grading scale chart, calculate a term grade with the weighted grade calculator, or use the final grade calculator to see what a student still needs on the exam.

Questions and answers
How do I use the easy grader?
Type the number of questions (or the total points) of your test, pick a grading scale and move the slider to the number of wrong answers. The grade, the percentage and the points appear at once, and the table below lists every possible score.
Which grading scale does it use?
You can choose the common A–F scale (A at 90% and up), a plus/minus scale (A+ at 97% and up), a 7-point scale, or your own cutoffs. The preset scales are widespread defaults, not official rules. Your school or district may draw the lines elsewhere, so use the Custom option to match them.
Can I use half points?
Yes. Switch on “Allow half points” and every row of the table steps by 0.5. The totals can have halves as well, for example 37.5 points.
Are my grades stored or sent anywhere?
No. All calculations run inside your browser. Nothing you type is sent to a server, and no student names are needed. Your last settings are remembered on your own device so they are ready next time.
How do I print the table?
Press “Print table”. You get a clean black-and-white sheet with the wrong-answer table and the cutoffs, formatted for Letter or A4 paper. Pick the paper size in your browser’s print dialog.
How is a score exactly on the boundary graded?
A score that lands exactly on a cutoff gets the higher grade. When an A starts at 90%, 18 of 20 points is an A. A score slightly below, such as 17.5 of 20, is a B.
