I wasn't sure about this because on places like [...] most kids were only talking about Barrons and Kaplan and other well known test prep books... but I found this one to be extremely helpful. It's meant not just as last-minute prep but to help you throughout the year, although I used it for last-minute. It's a really huge, thick book with lots of content. The practice tests were great, and there's a lot of solid advice that you can just sit down and read when you're in freak-out mode the week before the exam. I recommend it.
