I never dated when I was in school, if I could advise my past self I'd say try to get as many dates as you can because after school it dries up pretty fast... I'm 36 now and still single -_-.

The best time to plant a tree was 20 years ago, the next best time is today.

I think often we way over-weight environmental factors in this area. As individuals we have crazy amounts of agency to change things for ourselves. FWIW I barely dated in school, partly because I didn't care much for social interaction but also (maybe mostly) because I was quite clueless about romantic attraction. Since graduating and especially getting into my 30s, things have become so much easier.

Especially as a male, you can really change your situation by consistently choosing to invest in becoming a compelling partner.

Yeah but the girls in the 100 level course are required to be in that course to graduate almost for sure.

What else is it?

It's what you want it to be. Dating area, social network building place, source for information and tutors, source of certification, funnel to corpo jobs, etc...

Adult daycare? An expensive way to delay the onset of adulthood a few more years? An elaborate proxy for an otherwise-prohibited IQ test?

Mostly it's a piece of paper. For many professions, no matter how pointless the journey, that's a very necessary piece of paper.

Acculturation to bourgeois and haut bourgeois norms depending on the college, for elite colleges a way for the rich and those highly likely to be professionally successful to associate to the benefit of both, a way to launder IQ tests (the SAT and ACT), a four year holiday and networking opportunity, an entree into better jobs, a way to get the public to subsidise research they don’t understand. College has many purposes, just like school. They share the sorting and ranking function but for college there childcare one is much attenuated.
