I actually start prepping for finals in November (did it as a 1L also). This usually just means outlining and listening to the barbri cds. But then, I don't have to pull late nights studying in december. I think it all evens out as far as the time commitment involved, but I'd rather not end-load my study time and stress myself out.
Try not to listen to your classmates brag about already studying for finals. Most of them are just trying to psych you out because of their own fears of not doing well.
