The Formula

Test grade = correct ÷ total × 100

Understanding the Test Grade Calculator: Score Percentage from Points

42 correct answers out of 50 gives 84%.

Assumes equal points per question; use earned and possible points otherwise.

Worked example: 42 earned points out of 50 possible gives 84%. If a test has 20 equally weighted questions, 17 correct gives 85%. A score percentage does not determine a letter grade without the course grading scale.
