its the first day I don't know about where your going by my first day was a breeze day not a lot of "teaching" per say more of the course outline and meet and great with the professors my advice to you is to smoke a nice one on the way in and relax man its the same thing as high school sort of but with better evenings youll be fine
well in the case of being dry day 1 is a great time to make some new friends lol just looks for the people standing in a circle red eyed and walk over and strike up a conversation lol but all in all relax thhe next few years of your life should be among the best
