How to use it
- Type the number of questions on the test, and the points each question is worth (1 if every question counts the same).
- Choose whether the chart lists the number correct or the number missed, and whether half credit is allowed.
- Change the letter grades to match your school: start from a common scale and edit any letter or cutoff.
- Press Print to get the chart on one page, or use “Check one score” to grade a single paper on screen.
Ideas for class
- Print a chart for every quiz length you use (10, 15, 20, 25 questions) and keep them in a folder.
- Use “number missed” for a long test so you can count wrong answers and read the grade straight off the chart.
- Turn on half credit when you give partial points on short-answer questions.
- Change the scale for a mastery quiz: a single row at 80% called “Pass” and one at 0% called “Retry”.
- Tape the chart inside a cupboard door next to the answer key so grading goes faster.

Questions
How is the percent worked out?
Points earned divided by total points, times 100, then rounded to a whole number or one decimal, as you choose. A half rounds up, so 87.5% prints as 88%.
Which percent decides the letter?
The percent as printed. If you round to whole numbers, 89.5% prints as 90% and gets the A. If that’s not how your school does it, round to one decimal place and the letter will follow the decimal.
Is the letter scale the official one?
There isn’t one. The scales offered here are common starting points. Your school or district sets the cutoffs that count, so check them and edit the scale to match.
What if a question is worth more than one point?
Set the points for each question. The chart gets a Points column and the percent uses the total points on the test.
