How to Take the Practice Tests

Each self-test in this book consists of 60 questions; you should complete each test within 120 minutes. The number of questions and the time duration in the actual exam might vary but should be close to this number.

After you have studied the material presented in the preceding chapters of this book, you should take Practice Exam #1 to check how well you are prepared. After the self-test is complete, evaluate yourself using the answer key in Chapter 8, "Answer Key for Practice Exam #1." When you evaluate yourself, note which questions you answered incorrectly, identify the corresponding chapters in the book, and then read and understand that material before taking Practice Exam #2. After taking the second exam, evaluate yourself again and reread the material corresponding to any incorrect answers. Finally, take both tests again until you have correctly answered all of the questions. The information presented in the following sections should help you prepare for the exams.
