The book itself is broken out into 12 different chapters. There's also another ap called the anap, which has like a two dollar, 99 cent in at purchase for all the information with the types and as a version of the assessment that you can take in there. I took that one too, and that confirmed the results that i got from the r h e t i. So that one's probably pretty decent as well. Much less expensive the rh e t i, by the way, i think t was like 12 dollars. It really, really wasn't bad.
