How to calculate a test grade

Divide the points you earned by the total points possible, then multiply by 100.

Test Percentage = Points Earned ÷ Points Possible × 100

Example

A score of 42 out of 50 is 84%. The letter grade depends on the grading scale used by the course.

What is considered a passing grade?
