Grading scale

This is an editable example scale, not an official standard for any school or country. Letter grades are based on the exact, unrounded percentage — turning decimal display on or off changes only what is shown, never which grade is assigned.

Your grading scale is saved on this device only. No student names or scores are ever saved or sent anywhere.

Quick reference

Use Questions mode when every question on a quiz or test is worth the same amount — enter the total number of questions and either the number correct or the number wrong. Use Points mode whenever any question carries partial credit, extra weight, or a decimal score — enter the total points possible and either the points earned or the points lost.
