Query: The worst logic prep book I ever had...

People should really avoid this book unless you have too much money, time and effort to waste. Aside from this book only provides limited strategies on cracking the logic questions, it has way way way too many bloodly obvious mistakes in it answer keys. It only does two things: confuses you--because you will never understand the inference process since the answers are wrong; or frustrates you--one MORE mistake is found! I eventually got so frustrated that I had to abandon using this book after getting through about 1/5 of the book. Strongly recommend avoiding using this book.
