I give this 4 stars because pretty much any GRE review book will help you do better on the test. That said, I would recommend buying the Princeton or Kaplan books before the Barrons. They have a better layout and easier techniques to learn to solve the GRE problems. The Barrons guide seems haphazard in comparison.

Also, a full 1/4 of the Barrons guide is nothing but a 3,500 word list with definitions. This is a waste of paper. You really only need to know about 500 certain words for the GRE (from what I've been told) and you don't need full definitions only a general idea of what they mean. The other guides give you a more concise "what you need to know" vocabulary list -- Barrons is overkill.

I think the problem solving techniques of the other guides are also more effective. Barrons isn't a total flop, but you should consider the other guides first.

After comparing with other books, i've found that this one is the best choice, and the price it's also wonderful. Totally recommended!

Do not be fooled by the lure of "six full length model tests." The tests are in paper form. Barron's is a very paper-heavy book. You will get more practice through Kaplan's test prep as they have many computer-based exams.

i think the layout for the math section in this book is quite awful. i've always been pretty solid at math, and it was not user-friendly at all. verbal - the vocab list is quite massive, and if you have time to learn all the words, great. if not, at least learn the top 300 (and mix and match vocab lists between here [top 300 words, not the 3,500 list], princeton review, kaplan, and arco). the diags in the book, along w/ the CD were pretty good. the verbal is pretty accurate, but the math is harder than the real test. my verbal scores from barron's were around what i got on the actual exam, but my math score was higher on the real thing by a little bit. best combo in my opinion is PR and kaplan for technique, barron's for the vocab, and kaplan and barron's for realistic (albeit harder) sample tests.

Overall, I'm finding this book very well organized and easy to use. However, one of the reasons I picked this guide over others was because of the practice computer adaptive tests included on the CD-ROM in the back.
However, I have a Mac, and one without anything lower than OSX on it, at that. The CD-ROM requires Mac Classic for the practice tests, and for obvious reasons, I'm leery of installing a mostly-defunct OS on my computer.
I tried to figure out whether or not this would be a problem before I bought, but wasn't able to get a straight answer. So, Mac users, now you know -- this program hasn't quite made the jump to the current Mac OS!
