Easy Grade Formula With Example

1) Percentage Grade Formula

Percentage (%) = (Correct ÷ Total) × 100

2) Wrong vs Correct

If you know wrong answers: Correct = Total − Wrong

Example

Suppose your test has 50 questions and you got 7 wrong. Then Correct = 50 − 7 = 43.

Percentage = (43 ÷ 50) × 100 = 86%
