At the very least, get some of the books. There are definite strategies and patterns on the LSAT, so studying is absolutely required. That said, it's an odd test, because it doesn't really test knowledge, but instead your thought process. I will concur with Javeryh that the LSAT is worthless to know how well you will do in law school. It's a hoop to jump through, nothing more. I will admit I didn't exactly study as hard as many people did for it. I only purchased the Kaplan book and took some of the practice tests on the LSAT website, but I still did well enough on the test to get into Vanderbilt (I got into some higher ranked schools as well, but I liked Vandy better). I think the main preperation that is neccesary is simply being able to recognize exactly what kinds of questions you will be facing, and what those questions are actually asking. That just takes practice, and you should start as soon as possible. Best of luck.
