Test Grade Calculator
Quiz or test score and letter grade from questions missed.
Quick answer
How do you calculate a test grade?
Subtract the number wrong from the total, divide by the total, and multiply by 100. On a 25-question test with 3 wrong: 22 ÷ 25 × 100 = 88%, which is a B+.
Score % = (total − wrong) ÷ total × 100. Letter grade on the standard scale: A 90–100, B 80–89, C 70–79, D 60–69, F below 60, with + and − at 7 and 3.
