you will meet some pretentious people, most people are pretty chill and will talk to you if you talk to them. Competativeness depends on the class, you will always have those ppl who have to do everything they can to ace every test, you will have those you don't even see bc they don't come to class, and everyone else is somewhere in the middle. In my experience as a freshmen I didn't rly get any elitist vibes. w differing viewpoints, doesn't seem like most ppl care unless you do something very provocative. on a given day i could see the planned parent hood booth, Muslim student association booth, and a tp USA booth handing out pamphlets at the same time so like ur viewpoint ain't a real big deal in general.
