How to Convert a Score Out of 77 to a Percentage
To convert any score out of 77 to a percentage, divide the score by 77 and multiply by 100:

Frequently Asked Questions
What is a passing score out of 77?
On the standard 10-point scale, 60% is the passing threshold (a D). Out of 77, that means you need at least 47 correct to pass — 47/77 works out to 61%. Anything below 47/77 falls under 60% and is a failing grade.
How many questions can you get wrong out of 77 and still pass?
You can miss up to 30 questions out of 77 and still pass. Getting 47/77 correct gives you 61% (a D, the lowest passing grade). Miss more than 30 and you drop below 60%.
How many can you get wrong out of 77 and still get an A?
To earn an A you need 90% or higher. Out of 77, that means at least 70 correct (70/77 = 90.9%), so you can afford to miss at most 7 questions.
What is half of 77 as a percentage?
Half of 77 is 38.5, and 38.5/77 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 77 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 77 is first converted to a percentage — divide by 77 and multiply by 100 — then mapped to a letter. Your own school's cutoffs may differ, so check your syllabus.
