pur-Hints for Using This Book

Because this book is a paper practice product, you might want to complete your exams on a separate piece of paper so that you can reuse the practice questions again and again without having previous answers in your way Also, a general rule of thumb across all practice questions products is to make sure that you are scoring in the high 80% to 90% range for all topics before attempting the real exam The higher percentages you score on practice question products, the better your chances for passing the real exam Of course, we cannot guarantee a passing score on the real exam, but we can offer you plenty of opportunities to practice and assess your knowledge level before you enter the real exam When you have completed the exam on paper, use the companion CD to take a timed exam This will further help you gain confidence and make a self-assess- ment in case you need more study Your results will indicate the exam objectives

in which you need further study or hands-on practice.
