The best advice I can give you is to read everything over once. If you can, do it in one sitting, then re read it again. Then, read the sections again that you are not sure about, and if you can, get someone else to read it as well, and both of you make notes. There are plenty of website links in this book so it probably is best to read this book while you are online so you can see exactly what I'm talking about through out the book.
