I’ve found quite the opposite to be the case. In fact, the entire academic system is structured in such a way as to encourage students to experience a wide range of disciplines. You can think of it as a sort of liberal arts buffet - take whatever makes sense for you. In my case, I focus in political science and philosophy, but I’ve also taken courses in music, literature, and sound design. Next term I’m even taking an acting course. Because we all have different Plans, this collection of courses probably wouldn’t make sense for anyone else but me - so a lot of the fun is in finding the connections between different disciplines that intrigue you.
