Cherryblossom: Don't worry about it too much. I was out of school for over 10 years before law school. You read. You re-read. You write. You re-write. Oh, and don't forget to think and re-think.

That's essentially what law school is. To be honest, it ain't rocket science.
1) Is there anything that you wished you would have know before starting your 1L that you dont mind sharing? (I know that there are other boards that are meant specifically for this, but is there anything out there DU specific?)
No wishes. I researched it pretty thoroughly, about what the experience would be like. I TA'd for the legal writing program (Lawyering Process) last year and did find that many 1Ls weren't aware of the curve. So, if you didn't know, there's a curve. At DU it's a 3.0. Which is to say, the majority of students in every class will get a B. That concept can take some getting used to. Other than that, be prepared for the other curve: the significant learning curve of first semester (doesn't matter how old you are, everybody's in the same boat).
2) Do you have any experience with Law Review there? Are the write-on competitions pretty fierce?
I am on Law Review. The application happens at the end of the 1st year. It is rather intense. Typically, about 150 people download the application, but only 80-90 finish it. And approximately 30-35 are chosen. If you are interested in being on law review, there will be many info sessions about it, especially during the Spring semester. I am glad I am on it mostly for the friendships, the chance to meet some practitioners I wouldn't have otherwise, and the resume fodder.
3) Is there anyway to save money books wise, or does everyone just purchase at the book store? I hear that the e-books are becoming a big thing (especially since the iPad came out), would it be easier to just get the e-books? Can you print from the e-books?
I get my books mainly from Amazon (make sure you sign up for their Prime service as a student, once you get your student email!) and from the bookstore. Your biggest savings will be from ordering online. There is a used book deal that is run by the Student Bar Association, but I have never bought anything there, so I don't know what the quality is like. I'm sure the day is coming when law students will be able to annotate and highlight on an iPad, but that day is not yet here. Get the paper books and lots of 4-color pens and yellow highlighters (or your color of choice).
4) Im also kind of worried about the end of year exams. I haven't taken one in years (minus the LSAT, which was even a couple years ago). What did you find that worked for you?
Yes, the first semester of finals is daunting. But get your outline together, go through study problems if your prof offers any, or old exams, go thru them with friends, or use questions from the E&Es (Examples and Explanations series). Also, get used to IRAC. Issue, Rule, Analysis, Conclusion. It's the basic form for answering any test question.
5) Whats up with all the hype of supplements? Is that something only higher or lower ranked schools do? Do kids at DU use these things? Its just that it seems excessive.
I mentioned the E&Es. I have liked several of them, particularly for Civil Procedure (the Glannon book). Sometimes your profs will recommend ones. Or will even list them as optional for the course on their book list. Just ask around. Or look at some in the bookstore (they have all of them, all brands). Everyone learns differently, so it's hard to say if they are good or bad, or which ones are good or bad. You'll have to see what works for you and what works for that particular class (for example: my Crim Pro prof was very clear that he did not want to see answers that incorporated concepts from outside sources).
6) What is a typical day for you? Do you have time to do much else? Or for that matter of fact, did you as a 1L have any extra time to do anything else or does it seem like everyone just studies 24/7 including weekends? Is it possible to treat it like an 8am-5pm job?
It's exactly like a 9-5 job. I mean, like I said, everyone's different. Some people will be forever in the library. I found that I still had time to see the occasional movie, or hang out with friends. But other people struggled. Depending on where you're coming from, it can take a shorter or longer amount of time to learn how to read cases. Fortunately, for once, my English major came to the rescue. The only part of the LSAT that's worth a damn is the reading comprehension part.
7) How are the libraries? I took a quick tour and the facilities were beautiful, however, are they pretty crammed around finals, or are they always full with students? What are the hours like?
I'm not a library guy. I do like the study rooms, and yes, they can get booked early during finals. And the library gets crammed, too at that time. The library is fine. It has nice big tables with lamps and places to plug in your computer and jack into the internet (though there's WiFi too). It's not like you'll need access to the physical books. Everything is done on Lexis or Westlaw now. As for hours, I believe it's open until midnight.

What are the best places to get lunch? I dont really want to find myself eating with a bunch of undergrads, are the facilities pretty separated from one another?
DU is surrounded by various places to eat. I don't even know where the undergrad cafeteria is. We have a cafe in the forum of the law school. They have snacks and coffee and a sandwich/panini thing. Or you can walk across the street and hit Chipotle (the first one, in fact, the mothership as it were, though it is very tiny) or Subway, Bruegger's Bagles, Sbux, Noodles & Co is down the street, Tokyo Joe, and several local joints. Also, there are an unending series of lunchtime talks at the law school, M-Th, and they always have free food.
9) Are you specializing in employment law? Did you participate in the certificate program?
I am hoping to get the certificate. It's a new system, but basically you take 12 credits in one area, plus a "capstone" class and you get a notation on your transcript saying you completed the certificate program. As practicing employment law... we will see. As I understand it, you will pretty much wind up practicing the type of law of whoever hires you, given this market. But it's nice to point one's ship in a general direction and hope.
