I know a first year in your program. She is incredibly kind and welcoming (though maybe a little shy at first, in her first days at college), not snobby at all. She was virtual in 1st semester and has just come on campus in 2nd semester (along with quite a few other students obvs). Her description of the students in her classes is completely different than yours- overall. When I asked her if there snobby / cliquey girls she said ‘of course- you find those everywhere- but not many’.
If you don’t want to be there, you don’t want to be there- fair enough. But it is exceptionally unlikely that most of the nearly 500 people in your year (much less the other nearly 1500 people in your program) - in a communications program!- are unfriendly and “give nasty looks for no reason”. You don’t have to tell us your underlying reasons for leaving, but you need to know for yourself (see comment 1)
Your only sure choices so far are Boston or Chapman. Accepting that the costs are equal, and leaving aside their (extremely) different locations, to me the big dividing point is where your core interests are: if film Chapman, if journalism/media BU.
