Wonderful resource for studying for the exam. I used both the book and the online portion of the course and found that they covered different areas in a similar way. It was nice to see what was in each part, so I could study each at my own pace. The website is also a great resource as it provides you with practice quizzes, flash cards and other tools to make sure you are ready. Great study tool!
