How it works

How to calculate it

Divide the number of correct answers by the total number of questions, then multiply by 100. The letter label uses a common U.S. plus/minus scale.

Test percentage = (correct answers ÷ total questions) × 100

Worked example

Example calculation

If 46 answers are correct on a 50-question test, 46 ÷ 50 × 100 = 92%, typically an A−.

Before you rely on the number

Things worth checking

  • This page assumes every question is worth the same number of points. Mixed point values need the percentage grade calculator.
  • Teachers grading a full stack of papers usually want the EZ Grader, which prints one chart covering every possible number wrong.
  • If the test was curved, run the raw score through the grade curve calculator before reading the letter grade.
