I liked this book because it had more and better examples than the competition such as Lambers Review Course. It will not repeat practice excersices. It has pointers and tips on how to build knowledge in a logical and reinforcing way. The first time I took the exam I paid $1000 for a Lambers Review and I did not pass any part of the test. The second time, using Wileys Review books ( $129.99 approx.)I passed two parts.
