Congratulations on your application! I know its so hard to wait. As far as preparing, do not worry. You will have two orientations: a general one where they will give you a book list and immunizatiin requirements, etc., then another that is more detailed for your classes. Also, if you havent already I suggest signing up for USPS Informed Delivery. It's a service with the post office that sends you an email everyday showing pictures of what mail is being delivered that day. This way you can stalk your mailbox even if youre not home. :) I wish you the best of luck!
