How a 50-question test is scored

Divide the number of correct answers by 50 and multiply by 100. With 50 questions worth the same amount, each one is 2% of the grade. With 50 questions each answer is worth only 2%, so the grade is steadier than on a short quiz. This size is typical for midterms and multi-section exams.

On the common 90/80/70/60 scale you can miss up to 5 questions for an A, up to 10 questions for a B, up to 15 questions for a C, up to 20 questions for a D. Anything below the D line is an F.

Quick reference for 50 questions

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

0 wrong answers (50 correct) = 100.0%, grade A
1 wrong answer (49 correct) = 98.0%, grade A
2 wrong answers (48 correct) = 96.0%, grade A
3 wrong answers (47 correct) = 94.0%, grade A
5 wrong answers (45 correct) = 90.0%, grade A
10 wrong answers (40 correct) = 80.0%, grade B
15 wrong answers (35 correct) = 70.0%, grade C
20 wrong answers (30 correct) = 60.0%, grade D

Rounding and partial credit on 50 questions

Because 50 divides 100 evenly, every score is a whole percentage: no rounding is needed.

Half points are possible too: one half-credit answer is worth 1%.

Worked example: 6 wrong on a 50-question test

A student misses 6 of 50 questions.

Correct answers: 44 of 50
Percentage: 88.0%
Standard A–F: B
Plus/minus: B+

(50 − 6) ÷ 50 × 100 = 88%, so the grade is 88.0% (B).
