How a 25-question test is scored

Divide the number of correct answers by 25 and multiply by 100. With 25 questions worth the same amount, each one is 4% of the grade. A 25-question test is a common size for unit quizzes and chapter tests. One missed question costs 4 points, so a single slip rarely decides the letter on its own but two or three often do.

On the common 90/80/70/60 scale you can miss up to 2 questions for an A, up to 5 questions for a B, up to 7 questions for a C, up to 10 questions for a D. Anything below the D line is an F.

2 wrong answers (23 correct) = 92.0%, grade A
3 wrong answers (22 correct) = 88.0%, grade B
5 wrong answers (20 correct) = 80.0%, grade B
8 wrong answers (17 correct) = 68.0%, grade D
10 wrong answers (15 correct) = 60.0%, grade D

Rounding and partial credit on 25 questions

Because 25 divides 100 evenly, every score is a whole percentage: no rounding is needed.

Half points are possible too: one half-credit answer is worth 2%.

Worked example: 3 wrong on a 25-question test

A student misses 3 of 25 questions.

Correct answers: 22 of 25
Percentage: 88.0%
Standard A–F: B
Plus/minus: B+

(25 − 3) ÷ 25 × 100 = 88%, so the grade is 88.0% (B).
