Ok, I’m going to go backwards a step. What was it that you didn’t care for about Webster, apart from the fact that it’s in your hometown? They’re giving you a full tuition scholarship and the major in Film, Television and Video Production seems right up your alley and there are several other nearby majors that might peak your interest if things veer in a different direction, like Interactive Digital Media and Media Production, among many others. There’s this thread about going to college in your own hometown that might give you some ideas about how others have handled that very situation: Going to college in one's own hometown?. And should you switch to architecture, the savings from tuition could then be used toward that.
After going through the courses in the different departments at the three liberal arts schools and looking through Webster’s program, I really can’t see why you would want to go into such big debt for BU’s program.
