Hehe, it's not THAT bad, I think juniorgrrl is a tad bit stressed

Hon, I think you need to take a step back and relax and reevaluated why you're doing law school and why you're so stressed.
I'm stressed too, but not nearly to that extreme. Maybe my school's just different. I know it is a bit more laid back. But it's really not that bad. Of course, you've caught me on a good day. Other days I might be more inclined to speak of lawschool like juniorgrrl!
ANYWAY, as for prepping for the LSAT, it really depends on the kind of person you are and how you study. I did it on my own, using books. Prep classes are generally pretty expensive (upwards of $1000) and very stressful. I couldn't handle that, and it wouldn't have helped me that much. I did it myself and did just fine.
There's great books out there. The main thing is getting familiar with the examine and practicing, especially the logic games part.
