The most helpful book I found in my GMAT preparation, bar none. Most people taking this test rely on Kaplan, Princeton Review and then then think they’ve done enough. But those traveling the path to GMAT Mastery want to do better than everybody else.  So you’ll have to find references that nobody else has found (except fellow travelers on the path–don’t worry, there’s not many readers of this site yet!).

So are you really ready to walk that path of mastery? To do what it takes to boost your score by 50 or 100 points?  If so, then this book is the right place to start.  I’m not going to lie, it’s boring.  It’s a textbook! But it’s not just any old textbook. I am convinced this is the textbook that the test writer’s for the GMAT Critical Reasoning study when they are preparing this test.

If you are having trouble stating premises, identifying assumptions or are struggiling with other aspects of the critical reasoning section, go out and get this book right away.

Fortunately I found it at my local public library because I wouldn’t have forked over the $33.30 that Amazon is asking.  Having used this in my studying to such great success, however, I would definitely spend the $33 if I were starting over today.
