I’m quite positive that interior design is offered at other schools than the ones to which you applied.
Why did you bother to even apply to Casanovia and Suffolk if they didn’t have a course if study you wanted? Oh wait…they do!
http://www.suffolk.edu/college/undergraduate/15501.php Suffolk has an interior design major.
http://www.cazenovia.edu/academic-programs/interior-design and so does Cazenovia.
Are either of these colleges affordable?
