As a suggestion, research an array of private colleges, of which some may be receptive to the broader aspects of your application. Consider Colgate, Boston College, Vanderbilt and Notre Dame, for example. Along these lines, your chances at USC might be pretty good. For a less challenging admit, look into Trinity (CT). Consider UCSD for a slightly less selective alternative to UCLA.
