🅰️ Grade Calculator: Test Score Percent and Letter Grade Chart

How to use it

1. 1. Enter the number of questions

   Type how many questions the test has, from 1 to 200. The sample scale is already filled in, so you can press the button straight away and see a full table.

2. 2. Check the letter scale

   The example scale is A from 90, B from 80, C from 70, D from 60 and F below that. Change any letter or percent to match your own school, because scales differ.

3. 3. Choose rounding and make the table

   Pick whole-number or one-decimal percents and press Make grade table. Each row shows the number wrong, the number right, the percent and the letter for that score.

4. 4. Print it or grade by points

   Print the table and keep it next to your marking pile. For a paper marked in points, type points earned and points possible to get that percent and letter.

Ideas for class and home

• A marking chart for the whole stack

  Print the table for a 30-question test and tape it beside the pile. Count the wrong answers, look along the row, and write the percent. It is faster than dividing for every paper.

• Checking a rubric total

  Essays and projects are often marked out of odd totals such as 37 or 45. Enter the points earned and possible to get an exact percent without reaching for a phone.

• Testing a different scale

  Try moving the A line from 90 to 93 and see which scores change letter. It helps when you are deciding how strict a scale should be before the term starts.

• Homeschool records

  Parents keeping a portfolio can turn quiz results into percents and letters in seconds, and print the grade table for the folder as simple evidence of how scores were worked out.
