You would have a 60%.
According to my grade calculator with a 60 question test your break point would be 30 for a D- and a 57 for an A+, so an 80% would 47 correct questions and that means you would get a B and that is missing 10 questions.
Near enough the lowest possible!
your grade would be 80% or a B-
If there are 10 questions on the test then they are each worth 10 point to make a total of 100. If you miss one question, then you got 9 right (10 - 1 = 9) so 9 times 10 would be a grade of 90.
You would get a 94% for a grade which is typically going to be an A.
If you miss 5 questions on a 20-question test, you answered 15 questions correctly. To find your grade, divide the number of correct answers (15) by the total number of questions (20) and then multiply by 100 to get a percentage. This results in a grade of 75%.

If there are 10 questions on the test then they are each worth 10 point to make a total of 100. If you miss one question, then you got 9 right (10 - 1 = 9) so 9 times 10 would be a grade of 90.
To achieve a score of 90% on a 56-question test, you would need to answer 90% of the questions correctly, which is 50.4 questions. Since you cannot answer a fraction of a question, you would need to answer at least 51 questions correctly. Therefore, you can afford to miss 56 - 51 = 5 questions and still achieve a 90% score on the test.
To score a 40 on a 66-question test, you need to determine the minimum number of questions you can miss. Assuming each question is worth one point, you would need to answer at least 40 questions correctly. Therefore, you can miss up to 26 questions (66 total questions - 40 correct answers = 26 missed questions).
