Actually I did like this book and there are many useful tips there(considering that i've read at least 10 books from different companies before like Kaplan, Veritas, Official Guide,Mgmat), however, i wish this book had more problems like a huge problem set at the end of a book. I do recommend this book, but cannot fully understand if it helped me to make some progress. Need to do practice test first.
Solid, easy to understand and well presented. This guide really is the best I've read for gmat critical reasoning. My main ding revolves around the very few critical reasoning questions included in the guide.
The best book on GMAT Critical Reasoning I have ever seen. Although one may not find a lot of new information in the book, the information is presented in such a way as to improve your understanding and score.
