Webster's New World English Grammar Handbook, Second Edition

I was looking for a book to use as a study guide for the verbal section of the GMAT. As a college graduate, what I WASN'T looking for was a rudimentary book full of exercises, which is what the store bookshelves are full of. This book is more of a reference book, but it is laid out in a very intuitive and step-by-step manner, so it is useful as a study book. This was exactly what I needed, and for confirmation, I ended up getting almost a perfect score on my GMAT verbal.
