Query: It may help to use additional resources with the book

The pros about this book:1. I really enjoyed the sample problems in the book. It helped prepare me for the additional problems in the book.2. For the most part, I understood everything. Reading it was not too difficult.The cons about this book:1. Some answers were incorrect. I had to speak with the instructor to get a couple of problems cleared.2. The worst is that there is a solution manual available for only the Odd problems. I'd prefer a solution manual with both even and odd problems so that I can compare my work with and not hassle the professor's as much as i do to make sure i'm understanding the material.
