Before you begin Lesson 1, you may want to get an idea of what you know and what you need to learn. The
pretest will answer some of these questions for you. The pretest is 35 multiple-choice questions covering this
book’s topics. Although 35 questions can’t cover every concept, skill, or shortcut taught in this book, your performance
on the pretest will give you a good indication of your strengths and weaknesses. Keep in mind the
pretest does not test all the skills taught in this book.
