Scores Out of 8 as Percentages
Every possible score on a 8-question test or assignment, converted to a percentage and letter grade — from 0/8 (0%) all the way to 8/8 (100%). Below the chart you'll find how to do the conversion yourself, the key passing and A-grade thresholds out of 8, and answers to the most common questions.
How to Convert a Score Out of 8 to a Percentage
To convert any score out of 8 to a percentage, divide the score by 8 and multiply by 100:
percent = (score ÷ 8) × 100
example: (8 ÷ 8) × 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 8.
Common Scores Out of 8
The score you need out of 8 to hit each key percentage threshold:
- Passing (D, 60%) 5/8 (62.5%) D
- Half marks (50%) 4/8 (50%) F
- C grade (70%) 6/8 (75%) C
- B grade (80%) 7/8 (87.5%) B
- A grade (90%) 8/8 (100%) A
- Perfect (100%) 8/8 (100%) A
In short: you need 5/8 to pass (60%) and 8/8 for an A (90%).

Frequently Asked Questions
What is a passing score out of 8?
On the standard 10-point scale, 60% is the passing threshold (a D). Out of 8, that means you need at least 5 correct to pass — 5/8 works out to 62.5%. Anything below 5/8 falls under 60% and is a failing grade.
How many questions can you get wrong out of 8 and still pass?
You can miss up to 3 questions out of 8 and still pass. Getting 5/8 correct gives you 62.5% (a D, the lowest passing grade). Miss more than 3 and you drop below 60%.
How many can you get wrong out of 8 and still get an A?
To earn an A you need 90% or higher. Out of 8, that means at least 8 correct (8/8 = 100%), so you can afford to miss at most 0 questions.
What is half of 8 as a percentage?
Half of 8 is 4, and 4/8 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 8 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 8 is first converted to a percentage — divide by 8 and multiply by 100 — then mapped to a letter. Your own school's cutoffs may differ, so check your syllabus.
