But I've never met any 12th-grader who is so knowledgeable and wise that frosh year at a proper college shouldn't shake up their developing mind, and challenge much of what they thought they knew -- about the world, themselves, and even thinking itself.
(College is not a place to party and practice your whiteboarding theatre until you can get a FAANG job, knowing not much more than you did in high school.)
Whether it's in the humanities, social sciences, quantum physics, or even functional programming: if students are not surprised and uncomfortable at times, I'd think they're not learning enough.
