Why Buy? I've said it before, I'll say it again: The Princeton Review books are easy to understand. Sometimes, it's tough to figure out what you've done wrong on a particular question if you don't "get" the explanation. PR works hard to avoid those comprehension errors by writing readable text. In addition, the book, even with the additional practice tests, is much smaller than Kaplan's at only 880 pages, so if you're easily overwhelmed, this book may be more manageable for you.
