How it works
Subtract wrong answers from total questions. Divide correct answers by total questions and multiply by 100. The chart repeats this for every possible number wrong.
Worked example
On a 50-question test with 4 wrong answers, the student has 46 correct. The score is 46 ÷ 50 × 100 = 92%, typically an A−.
