I was at Barnes and Noble yesterday, checking out some of the LSAT prep books. I work for one of the companies and was just curious about some of the other methods out there.
The first one I looked at was http://www.amazon.com/Cracking-Edition- ... 0307944735 - as far as I know, this book is extremely popular and we all know the huge name Princeton Review has in the undergraduate/graduate world of admissions and test prep.

Unfortunately, despite the good work that the online blogs have done, and the progress made in transparency, people are a lot more likely to take the advice of a respected, seemingly unbiased third party like the Princeton Review. And they reach a lot more applicants.

On the other hand, maybe demonstrating how critical the LSAT is to a legal future would increase the number of people taking the course or buying the materials?
