It's more hassle than it's worth for the first round of classes, but once you start reteaching things your prep time probably drops to 30 min per class. So for a half hour our of class and two hours in, you earn $42. That's a pretty easy way to make money. And it's not like real teaching where you really have to be interactive -- 90% of it is jus reading/following the book. Also, in my experience (2 LSAT classes plus some SAT, ACT, GRE - so not too much) the pre-course score range is probably 145-162 so if you scored in the mid 160s or better, you will probably be able to answer a lot of their questions on the fly.
