Best LSAT prep book or online program

Would you please recommend best book or online program for someone who has couple of months to prepare for a test?

there are a bunch of resources out there, including the PowerScore books, Kaplan, Princeton Review, and the like. Personally, I’m a fan of Manhattan.

But you might see if you can carve out 3 months for prep. It’s that important and a high score can result in thousands of dollars in tax-free merit money.
