Peterson's GMAT Success [With Free]

I am currently studiing for the GMAT and using this book as well as others. I am centering my study around this book and using the others as add ons, for different perspectives, and for additional practice tests. The course is thorough. The book breaks down each part of the test into types of questions that are asked. Most importantly the book gives a math or grammer lesson to teach you what you didn't know or forgot. I like this better than other programs that give you "tricks" to solve problems. I prefer to understand the underlying knowlegde. That is why this book is better than the other books that I've seen. My one complaint about the book is that their sample questions are poor. The reading comprehension passages were incomprehensible and the questions were poorly worded and confusing. I was very concerned until I consulted other references and realized I that it was the book and not me. One sample math question required some little math rule that I have never heard of or ever seen in a book. Good luck everyone! -MR
