Scores Out of 9 as Percentages
Every possible score on a 9-question test or assignment, converted to a percentage and letter grade — from 0/9 (0%) all the way to 9/9 (100%). Below the chart you'll find how to do the conversion yourself, the key passing and A-grade thresholds out of 9, and answers to the most common questions.
How to Convert a Score Out of 9 to a Percentage
To convert any score out of 9 to a percentage, divide the score by 9 and multiply by 100:
percent = (score ÷ 9) × 100
example: (9 ÷ 9) × 100 = 100%
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 9.
Common Scores Out of 9
The score you need out of 9 to hit each key percentage threshold:
- Passing (D, 60%) 6/9 (66.7%) D
- Half marks (50%) 4.5/9 (50%) F
- C grade (70%) 7/9 (77.8%) C
- B grade (80%) 8/9 (88.9%) B
- A grade (90%) 9/9 (100%) A
- Perfect (100%) 9/9 (100%) A
In short: you need 6/9 to pass (60%) and 9/9 for an A (90%).

Frequently Asked Questions
What is a passing score out of 9?
On the standard 10-point scale, 60% is the passing threshold (a D). Out of 9, that means you need at least 6 correct to pass — 6/9 works out to 66.7%. Anything below 6/9 falls under 60% and is a failing grade.
How many questions can you get wrong out of 9 and still pass?
You can miss up to 3 questions out of 9 and still pass. Getting 6/9 correct gives you 66.7% (a D, the lowest passing grade). Miss more than 3 and you drop below 60%.
How many can you get wrong out of 9 and still get an A?
To earn an A you need 90% or higher. Out of 9, that means at least 9 correct (9/9 = 100%), so you can afford to miss at most 0 questions.
What is half of 9 as a percentage?
Half of 9 is 4.5, and 4.5/9 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 9 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 9 is first converted to a percentage — divide by 9 and multiply by 100 — then mapped to a letter. Your own school's cutoffs may differ, so check your syllabus.
