@dantlee14 thanks for the list! I wish more schools did the interview! I know the application speaks for itself on your behalf, but sometimes being F2F is a more personal approach. Oh well :smile:
I'd say no. Disliking a major isn't really a good reason for an addendum, imo. Just apply and see what happens. if they for some reason ask you about it in an interview then just tell them, but yeah don't do the addendum
