To find out how many questions you can get wrong, subtract the number of correct answers from the total number of questions: 55 total questions - 44 correct answers = 11 questions wrong. Therefore, you can get 11 questions wrong on a 55-question test and still achieve an 80% score.
If a test has 150 questions and you are aiming for a perfect score, you can get a maximum of 0 questions wrong.
