Grading chart

Letter grade scale (editable)
GradeFrom %Remove

Built for grading a stack of papers

The fastest way to grade a pile of tests is not to calculate each one. Print the chart once, keep it beside the pile, count the wrong answers on each paper and read the percentage and letter straight off the sheet.

  1. Enter the number of questions (or the total points).
  2. Check the grade scale matches your school's, and edit it if not.
  3. Press Print chart. Only the chart and the test details print, in columns.
  4. Mark each paper, count the wrong answers, and look up the row.

For tests where questions carry different marks, switch to Points and choose a half- or quarter-point step if you give partial credit. If every question is worth the same, keep Questions mode and set the points per question, so a 20-question test worth 5 points each is charted out of 100.

Worked example

A 20-question quiz. A student gets 3 wrong, so 17 right.

17 ÷ 20 × 100 = 85% → B (A 90, B 80, C 70, D 60)

The same rows from the chart:

What this calculator does not do

  • Charts are limited to 2,000 rows (for example 2,000 questions, or 1,000 points in half-point steps).
  • The default letter scales are common examples, not your school's official policy - check and edit them.
  • It does not store class results; use your gradebook for that.

Frequently asked questions

How does an easy grader work?
It divides the number of correct answers by the number of questions and multiplies by 100. For a 20-question test, 17 right (3 wrong) is 17 / 20 × 100 = 85%. The chart does this for every possible score at once.
Can I count wrong answers instead of right ones?
Yes - most teachers mark the wrong answers, so that is the default. Switch to "Number right" if you prefer.
What if questions are worth different points?
Use points mode: enter the total points on the test and the step (1, 0.5 or 0.25 points). The chart then lists every possible points score. If every question is worth the same, set "Points per question" instead.
Can I change the letter grades?
Yes. Pick the A-F scale or the plus/minus scale, or edit any cut-off and label in the grade scale table. The chart updates as you type.
How do I print the chart?
Press "Print chart". Only the chart and the test details are printed, laid out in columns to fit on one page for most tests.
How are percentages rounded?
To the number of decimal places you choose, rounding halves up. The letter grade uses the rounded percentage shown in that row.
