7sage has great vids uploaded for the game sections! JY I personally think he's a little funny but I think he does a good job explaining the games. I've never taken their classes but heard they are good (hence the users above, lol).

Sidebar has a good amount of resources posted! --->

Graeme (mod) also teaches LSAT ... Not sure if it is full time, but if you're not in the area I think I remember him saying he's done it via Skype. Also he has really good explanation books out for the pt's! Check out amazon. Which is awesome bc a lot of the LSAT and doing well is knowing why you got the answer BOTH right and wrong. :D -wow I sound like an advertisement lol.

I personally didn't time myself in the beginning. Then once I'm comfortable with the sections ... I started timing myself. At first individual sections then full pt. I worked on a timed test maybe once a week and then more frequently towards the test date... Working on from older pt to the newer ones.

If you're looking for a certain schedule to set for yourself ... I hear lsatblog does a good job of this. http://www.google.com/search?q=lsatblog&btnG=&biw=320&bih=263&sa=2

I use this app that is out for both iOS and android called LSAT proctor by Kaplan. I absolutely love it.

Hmmm lol this is long enough I bet. Sorry for that. Anyhow ...

Just wanted to note that I'm using my phone to post so there may be tons (or little -hopefully) of grammatical errors and I'm hoping the links above works. Apologies of they don't.
