How to Grade a 100-Question Test
Grading a 100-question test is straightforward once you know the formula. Divide the number of correct answers by 100, then multiply by 100 to get the percentage. Then match that percentage to the grading scale.
The Formula
(Correct Answers ÷ 100) × 100 = Percentage
Then use the grading scale: A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F = 0-59%
Worked Example
Xavier’s comprehensive final exam: Xavier got 85 correct out of 100. Their score is (85 ÷ 100) × 100 = 85%. That’s a B (solid performance).
What Each Question Is Worth on a 100-Question Test
On a 100-question test, each question is worth exactly 1.0% of your grade. This means every single question matters.
Understanding per-question value helps you make quick estimates. If you miss one question, subtract 1.0% from 100% to get your score. Missing two questions? Subtract 2.0% from your total.
💡 Pro Tip: 100-question exams are used in standardized testing and AP courses
To reach a passing grade (60%), you need to get at least 60 questions correct out of 100. Use our test grade calculator to explore what-if scenarios, or check the grading scale calculator for other test lengths. If you need to work backward from a target grade, try our grade calculator.
