I'll be going into my second year and I'm looking forward to it. Here's my unsolicited advice to all incoming 1Ls...
1) many many people will try to get you down about going to law school and becoming a lawyer. omgsomuchwork, hatelife, etc. don't listen to them. most of them don't have firsthand experience and don't know what they're talking about. I know some people that are miserable at my school and others who are quite happy.
2) almost everyone will have advice for you on what you "need" to be doing - study groups, outlines, etc. the sheer volume of advice can be frightening. if something somebody says sounds good, try it out. if they sound like they're full of [censored], they are. carve your own path, don't follow someone else's.
3) trust me, no one has any [censored] clue what is going on at first. I didn't really "get" law school for the first 2.5 months.
4) I maintain that law school is as much work as you want to make it. I knew 1Ls who spent hours in the library every night and others who went out 4 nights a week.
5) grades are much more arbitrary than undergrad. typically, 100% rides on a 3 hour open-book, essay final. a large portion is just how good of a first draft writer you are. personally, I have experienced a reverse correlation between amount of effort put into a class and the grade I received.
