Brush your teeth, shave, wear something nice, maybe a suit. Dont bring listerine in your handcarry, it will mess up your nice white dress shirt. Well, in my case it did.
Stay calm, easier said than done. I try to stay calm but when it was time to answer questions, I (and other applicants) had that shaky, nervous delivery with our answers. It's definitely nerve racking.
Smile. Breathe.
How long did they say the interview was? Does it include a tour, is it a group interview? Usually if it is a group interview and includes a tour, the interview part will probably fly by. There isn't really enough time for it to be like an hour interview if your scheduled to take the tour, pre-req check, lunch, etc.
Have fun. Have you gotten accepted from another school already? This definitely helps calm the nerves, knowing if you messed up at least you still have a back up.
