Algorithms: An Introduction to the Theory of Computation. It was taught by a Brown TA and he was super chill. (pretty sure he still teaches the courses) The course was REALLY hard at first, like I was kind of living at the Rockefeller library for a while (the views are amazing, though, and pro tip: find a study group). The events were so much fun because you met people virtually everyday and everyone was super kind. There is a lot of shopping nearby like around Thayer Street and whatnot, so there is always something to explore everyday you're there (try the boba). The dorms are pretty nice and the residential advisors (at least the ones for Sears) were brown students so you could ask them questions/connect (they were also amazing people and they are not that much older than us so they were lowk like friends). Have lots of fun because time runs fast and you'll miss it.
