I know two people who are research assisting for a professor in whose class they both consistently spoke up in (read: every day) and made A's in, but I haven't heard of any other 1L's securing that kind of position.
As for the social aspect, I agree that "cliquey" may be the wrong word. I have a close group of friends in my section, but some of my very best friends are in other sections, and I feel that the students here in general are very friendly and very eager to meet new people. Additionally, while the 1Ls may not be super close w/ the 2 and 3L's, I've managed to make friends w/ both just by interacting w/ people in the library and at social events. I'm not necessarily one to make friends easily, but I had no problem coming here. I met tons of people during orientation, and you don't have to go out all the time to be in the know about things. That being said, law school is vverry high school when it comes to gossiping and hooking up, etc. I think part of the problem is that most of us are so busy w/ school that when we do go out it is usually to a law school event (either sponsored by SBA or just a party/going out thing that everyone knows about), and so you are around the same people constantly. That mixed w/ alcohol usually leads to someone hooking up w/ someone who was previously hooking up w/ someone else, or whatever. I went to fsu for undergrad, but most of my friends have left tallahassee, and I RARELY see the ones who are still here b/c most of my life revolves around law school, including the social aspects.
As for professors, some are better than others, but I have been impressed overall. Additionally, I know there are professors that I hate that other students love, and vice verse, so any one person's opinion shouldn't really count for much regarding each professor. I think in the end you are learning it all on your own anyway, and anyone who says they learned the bulk of the material reading and sitting in class everyday is just not being honest with themselves. I mean, it definitely helps when you do the reading and show up to class and participate and take notes, but in the end you are going to be relearning everything from the beginning anyway to prepare for exams, which i'm sure you all know is the only thing that matters.
Crime in tally, I've lived here for almost 6 years and I've never been a victim of crime, but it does happen (robberies, rape, etc.). I think like everyone else said, just be careful and know where the bad parts of town are. In general, I feel safe at FSU and have spent many a night there after hours w/o incident. It's definitely not to a level that would warrant hesitation in attending.
OCI for 1Ls seemed a little slim to me, but this is probably b/c I'm looking to stay in tallahassee for the summer, and a lot of the OCI positions are in other places, either other FL cities or GA or AL. I have spoken to quite a few 2 and 3L's on the matter, however, and work is out there if you are persistent. A couple of my older friends have told me they just mass mailed their resume and cold called places until someone would hire them. Some positions will be unpaid, but apparently this is more like a test, and if you do decent work after a week or two they will pay you anyway. The placement office is beyond helpful. They took my resume and transformed it into something submittable, and changed things I would have never thought to. The placement office Symplicity program is also immensely helpful, as there are tons of firms listed on there seeking 1Ls that do not participate in OCI.
As far as complaints, I am the wrong person to ask. I went into law school as blind as the next person, did a moderate amount of work during the semester, and skipped most of my classes at the end to outline and study. I ended up in the top 20%, but feel that those in the top 5-10 truly deserved it as they were the ones notorious for studying all day, everyday. In general, people don't talk too much about grades, but you can kind of figure out where people ended up. I think most people ended up where they were supposed to. I have friends that did amazing, and friends that did not so hot, and I think it comes down to knowing how to take exams and understanding what it is they are truly looking for.
Not sure what else to write, but I do not regret coming to FSU. I am in state so for me the higher ranked schools I got into were not worth the increase in price. I feel like I'm getting a quality education at a school that I truly love for 1/2 of what I would pay somewhere else.
The end, good luck!
