Pretty much what the title says. What did you "forget" to bring (didn't think you needed or overlooked) when you went to visit and interview colleges?
Later this month I have my first three interviews, all out-of-state. I am eager to hear what things you ended up needing when you visited and stayed at the campuses and when you interviewed. I try to travel light, but I don't want to miss anything that other students who have been there really ended up needing. Even if you didn't forget it/ didn't have it, what were your most important tools?
For example, did you really wish you had a pad of paper that you carried with you to jot notes down? Did you regret the fancy shoes you wore? Did you not have information you needed with you?
