You will have 90 minutes to complete the exam, which consists of 60 questions. You will need to get at least 42 correct. Take care in reading each question, looking for details that would rule out any of the answers. Many times there will be two or more apparently correct answers, while only one correct answer is truly acceptable. In that case, choose the most correct answer. Leaving a question blank will count against you, so you are always better off taking your best guess. It’s best to work through the entire test once, answering the questions that you can easily answer. On the second pass, work on the more difficult questions. Others you have already answered could help you answer the remaining questions.
