What grade is 2 wrong out of 10?

2 wrong answers leaves 8 correct, which is 80.0%. That is a B on the standard A–F scale and a B- on the plus/minus scale.

Can I give partial credit on a 10-question test?

Yes. On a 10-question test, turn on half points in the Quick Grade calculator and a half-credit answer counts as 5% instead of 10%. The chart on this page uses whole questions only.

How a 10-question test is scored

Divide the number of correct answers by 10 and multiply by 100. With 10 questions worth the same amount, each one is 10% of the grade. On a short 10-question quiz every single answer matters: one missed question moves the score by 10 percentage points, which is often enough to change the letter grade.

On the common 90/80/70/60 scale you can miss up to 1 question for an A, up to 2 questions for a B, up to 3 questions for a C, up to 4 questions for a D. Anything below the D line is an F.

Quick reference for 10 questions

These scores come from the same chart you see in the tool above.

0 wrong answers (10 correct) = 100.0%, grade A
1 wrong answer (9 correct) = 90.0%, grade A
2 wrong answers (8 correct) = 80.0%, grade B
3 wrong answers (7 correct) = 70.0%, grade C
4 wrong answers (6 correct) = 60.0%, grade D

Rounding and partial credit on 10 questions

Because 10 divides 100 evenly, every score is a whole percentage: no rounding is needed.

Half points are possible too: one half-credit answer is worth 5%.

Worked example: 1 wrong on a 10-question test

A student misses 1 of 10 questions.

Correct answers: 9 of 10
Percentage: 90.0%
Standard A–F: A
Plus/minus: A-

(10 − 1) ÷ 10 × 100 = 90%, so the grade is 90.0% (A).

Clear, mathematically verified answers to common questions about weighted grade averages, grading scales, and final exam target scores.

Each question is worth 100 ÷ 10 = 10% when every question has the same weight. Missing one question leaves 90%, and each further miss lowers the score by another 10 points.

On a 10-question test with the common 90/80/70/60 scale you can miss up to 1 question for an A. For the other letters you can miss up to 2 questions for a B, up to 3 questions for a C, up to 4 questions for a D. Your teacher’s scale may use different cutoffs, so check the syllabus.
