Every possible score on a 54-question test or assignment, converted to a percentage and letter grade — from 0/54 (0%) all the way to 54/54 (100%). Below the chart you'll find how to do the conversion yourself, the key passing and A-grade thresholds out of 54, and answers to the most common questions.
How to Convert a Score Out of 54 to a Percentage
To convert any score out of 54 to a percentage, divide the score by 54 and multiply by 100:
percent = (score ÷ 54) × 100
example: (49 ÷ 54) × 100 = 90.7%
The resulting percentage is then mapped to a letter grade on the standard 10-point scale. The full table below has already done this for every score out of 54.

Frequently Asked Questions
What is a passing score out of 54?
On the standard 10-point scale, 60% is the passing threshold (a D). Out of 54, that means you need at least 33 correct to pass — 33/54 works out to 61.1%. Anything below 33/54 falls under 60% and is a failing grade.
How many questions can you get wrong out of 54 and still pass?
You can miss up to 21 questions out of 54 and still pass. Getting 33/54 correct gives you 61.1% (a D, the lowest passing grade). Miss more than 21 and you drop below 60%.
How many can you get wrong out of 54 and still get an A?
To earn an A you need 90% or higher. Out of 54, that means at least 49 correct (49/54 = 90.7%), so you can afford to miss at most 5 questions.
What is half of 54 as a percentage?
Half of 54 is 27, and 27/54 is exactly 50%. Under the standard 10-point scale that is a failing grade (F), since 50% is below the 60% passing line.
Is a score out of 54 graded on a 10-point scale?
Most US schools use the standard 10-point scale regardless of the denominator: A is 90%+, B is 80%+, C is 70%+, D is 60%+, and anything below 60% is an F. A raw score out of 54 is first converted to a percentage — divide by 54 and multiply by 100 — then mapped to a letter. Your own school's cutoffs may differ, so check your syllabus.
