Going to take the LSAT in October, just started prep yesterday...

This might be too late in the game to be helpful, but here goes. I had a math background, and had taken a formal logic course in college. I know I gained a lot of speed on the test by breaking down many of the logical reasoning & analytical reasoning questions in these terms. So, if you have a math or computer science background, it might be worth it to go through the introductory chapter of a formal logic book.

Another thing that some of the prep companies tell you to do, and I found helpful -- get a (well-written / major) daily newspaper and (i) do the SuDoKu puzzle (logical reasoning) and (ii) critically read the editorials (break them down -- purpose, thesis, etc.; all the question styles that are asked in reading comprehension). It doesn't take very long, and helps you practice for the test in a way that doesn't feel like you're practicing for the test.

Good luck.
