Hello,
I am a senior in high school, and I go to an arts driven high school. It has not been my favorite, I don’t hate it, but don’t mesh that well with super artsy kids, partially politically. I am interested in RC because of the close community, small classes, and the language requirement. Will I still enjoy RC?
Choose an RC for exactly the reasons you stated - not the social scene. There is plenty of opportunity for social stuff outside the academia.
Also, your first year is a time of exploration and you might find a different area of study more interesting than the one you just locked into for the year if you are LSA.
You listed the best reasons to join the RC. There are even conservative professors - and students - in the RC, so you won’t be alone. It’s a great environment with a lot of positive people of many persuasions.
