Besides going on a campus visit, signing up for the mailing list or applying early, is there any other ways to show demonstrated interest? Also, if the campus is far, can you show adequate interest without visiting campus (if there is no local college fair or info session) ?
There have been several threads about this here on CC. The ultimate way to show interest is to apply ED if that is feasible. Another way to show interest is to write your essays specific to each college instead of copying and pasting.
