20 out of 24 means 4 wrong answers

Scoring 20 out of 24 is the same as getting 4 wrong out of 24. Both describe one result: 20 correct answers on a 24-question test. Whether your teacher counts up from correct answers or down from wrong ones, the percentage is identical.

How the 20 out of 24 percentage is calculated

The percentage comes from one division: 20 ÷ 24 × 100 = 83.33%. Every question on a 24-question test is worth 4.17% of the total score.

Why 83.33% is a B on the standard scale

The standard 10-point scale puts a B between 80% and 89%, so a 83.33% test earns a B. That converts to a 3.0 on the 4.0 GPA scale.

How many can you miss on a 24-question test?

Every letter grade on a 24-question test has a maximum number of wrong answers.

Letter grade cutoffs for a 24-question test

A — at least 22 correct (miss no more than 2 questions)
B — at least 20 correct (miss no more than 4 questions)
C — at least 17 correct (miss no more than 7 questions)
D — at least 15 correct (miss no more than 9 questions)

Anything at or below 14 correct falls under 60% and is an F on this scale. Your own class may round differently or use a curve, so treat these cutoffs as the common default rather than a rule.
