How the Easy Grader Works
The easy grader subtracts wrong answers from total questions, divides the correct answers by the total, and converts the result into a percentage.
Score = Correct answers / Total questions x 100
Example: on a 25-question test with 3 wrong answers, the score is 22 / 25 x 100 = 88%, which is a B on the default scale.
