Congrats bro...best piece of advice I got my freshman yr was at our first freshman orientation. The gym was packed. The speaker said look to your left, now look to your right. Half of the people you see won't be here next yr so you need to do what you need to do with your classes so that you don't flunk out because it can and does happen all the time.
Have fun but don't get caught up in the party life...focus on what you came there for. Good luck
