How a 16-question test is scored

Divide the number of correct answers by 16 and multiply by 100. With 16 questions worth the same amount, each one is 6.25% of the grade. A 16-question test is a common size for unit quizzes and chapter tests. One missed question costs 6.25 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 1 question for an A, up to 3 questions for a B, up to 4 questions for a C, up to 6 questions for a D. Anything below the D line is an F.

Rounding and partial credit on 16 questions

Because 16 does not divide 100 evenly, scores are rounded. For example, 2 wrong is 87.5% exactly and shows as 87.5% rounded to one decimal. The letter is chosen from the rounded value that is displayed.

Half points are possible too: one half-credit answer is worth 3.125%.

Worked example: 2 wrong on a 16-question test

A student misses 2 of 16 questions.

Correct answers: 14 of 16
Percentage: 87.5%
Standard A–F: B
Plus/minus: B+

(16 − 2) ÷ 16 × 100 = 87.5%, so the grade is 87.5% (B).
