Thanks for all of the great advice. I have one question- how are we, as beginning students in the law, actually supposed to be able to figure out why the law was included? To me, all I see in this case is that airplanes aren't considered motor vehicles. Is that really the big picture I am supposed to get out of this case?
Probably all you are supposed to get out of it. One thing you will learn is that sometimes in law school you need to take things at face value. Cases often only provide you with insight like that. That simple. The only logic/analysis you will have to do is when your prof gives you an exam and you have to decide whether a blimp (or something like that) is closer to how they define a motor vehicle or closer to how they define airplanes. The case could be as simple as that.
Dont stress law school. Most people graduate (at least at the respectable schools) and most people get jobs after, and I assume most people are able to pay back their loans when they are done.
Enjoy yourself and try not to be too worried about the whole thing. Very few people know what to do in law school when they first start (I had no clue how to brief, how to outline, or really what we would do in class). Before you start, watch Paper Chase, get scared, then go to school and realize that its not scary and its not difficult and you aren't the only one that is learning as you go.
