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.
