First Sam, Don't confuse yourself. If you can prepare from book - MORE POWER TO YOU.
Book is dry and boring and you have to figure out how they are going to ask questions.
I did it with book. This site did not have questions on every chapter when I passed. There were only few question on chapter 2 at that time. Now they have questions on every chapter. You will evantually study everything in the book but small portion at a time. With quizez provided here, you can easily practice while you read a portion. You can also go with your pace and read one chapter at a time.
Test is based on the book and not on this web site - That is a FACT - No IFs and BUTs about it.
Then again you get more help from this Web site as this is based on the book and people who already has taken test. These people are helping others to pass the test without getting confused.
One good thing about this site is that they have also copied the text for chapter 2, 3 and 4 so buying book is really not necessary. I am not sure if they have full text of all three chapter but other people will let yo know if it's all there.
Last suggestion: Even if you prepare yourself with the book, don't forget to go through all the quizes on this Web site for all three chapters. That will lamost guarantee yo a pass result.
Hope this helps.
Are you still confused????
