If a test has 150 questions and you are aiming for a perfect score, you can get a maximum of 0 questions wrong. However, if you are allowed to get some questions wrong and still pass, it depends on the passing criteria set by the test administrator. For example, if the passing score is 70%, you can get up to 45 questions wrong (150 questions * 30% incorrect = 45 questions).
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
To achieve an 80% score on a 55-question test, you would need to answer 44 questions correctly (55 questions x 0.80 = 44 questions). 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.
In order to score exactly 70% on a test with exactly 70 questions ... if every questionis worth the same credit ... you have to get 21answers wrong. You can do it.
Your score on a test is based on the number of questions answered correctly, so the score is 35/47 = about 75%. The letter grade for that score is completely the teacher's decision.
