Pretty much the usual. Relax, go with the flow, make sure your classes are prepared ( the most important thing ) and don't try and do too much too soon. One other thing, keep your mouth shut when it comes to gossip. Obviously I am not saying that you are the type to gossip, but the quickest way to end up as "billy-no-mates" in my school is by gossiping about things you know nothing about. Hmm. I think that is it. There is one other, but there are two schools of thought on this one. My personal opinion is to keep quiet in discussions unless you really know what you are talking about for the first 6 months or so. Others believe that you should speak your mind. I think what you say is listened to more if people know that you have expertise and are not the sort to offer an opinion on everything. Good luck though.
