I'm a good bit older than you (Class of 1980). I lived with a bunch of engineers, and they were pretty dedicated to becoming engineers. I do recall one guy who dropped out of school (and eventually returned), but he was a mess to begin with. My gf at the time was pretty exceptional (SAT > 1500, when that actually meant something!), and she managed. Likely pretty rare, I guess. I don't think I knew any ex-engineering students, but I didn't ask, and I was engineer-adjacent (CS).
I applied to schools with architecture programs (Cornell, Rice, Carnegie Mellon), but once I saw what the School of Architorture demanded, I committed to computer science.
There was a guy i knew in my class who was on the wrestling team and graduated with a degree in landscape architecture. One of my senior year housemates was a co-captain and got into medical school. What a work ethic these guys had.
