Finding the right LSAT prep provider can be a daunting task. The sheer quantity of companies that claim to provide services is staggering, and you always run the risk of paying money for poor prep products--or worse, getting scammed and not getting anything at all.
I posted this on another thread, but thought it might be helpful for others to know about this resource: Accepted.com's special report,
"LSAT Prep Companies: In Their Own Words." It's a really good, lengthy, information-wealthy PDF available for free on Accepted.com, and it basically has interviews with the heads of the bigger test prep companies out there:
► Atlas
► Princeton Review
► Get Prepped
► PowerScore
► Kaplan
► Knewton
► Inspirica
► Test Prep New York
► Blueprint
If you're only now starting to look into companies for your LSAT prep, it's worth it to take a few minutes and read through the report. It's an interesting, easy read, and it will give you a good idea of what each company values, what they highlight in their courses, and how they structure their prep. It will also give you a good idea of comparison points between each company and what you should ask when calling each of them. I, personally, found it really helpful.
