If you miss 6 questions you will get an 85% on a 40 question test. To calculate various test score questions, simply divide the number of correct answers by the number of total questions. For example, on your particular question, if you divide 34 (the number of correct answers) by 40 (the total number of test questions), the answer is .85, or 85%.
