I'm coming into this thread late, but I agree on the don't get plastered in front of the classmates. It becomes the stuff of legend, but probably not in the way that you want to be remembered. I'll add a caveat to this -- if you do go out and get drunk, don't go home and drunk-mail your entire section. That's just self-memorializing the stupidity.
Personally, I stopped drinking several years before school started. Sometimes I go to socials, and I get along fine w/out drinking at 'em.
