Frequently Asked Questions
How is a test grade calculated?
Subtract the number of wrong answers from the total questions to get correct answers. Divide correct answers by total questions and multiply by 100 to get the percentage. For example, if you get 21 wrong out of 100 questions, you have 79 correct answers, which equals 79%.
