This introduction provided background information and general hints on what to expect from the exam, what to do in order to take the exam, what happens on the day of the exam, and what happens once you have passed the test. Advice on how to understand the questions was provided as well.
When you are done studying the chapters (and answering all the example questions!), and are ready to sign up for the exam, you should return to this introduction and re-read the sections on taking the exam. That way, you are fully prepared for the exam when the day arrives.
