For most of the college experiences we talk about on CC, our kids are adolescents until at least graduation. That’s not to say they’re children, but in the process of transitioning. How long it takes depends on the kid (and us.) Some are very mature, but I don’t think maturity alone is the factor. Adulthood a different sort of juggling than classes and personal responsibility. Enjoy youth while you can. If you’re lucky, as an adult, you’ll still be able to lean on close friends and family. But just as often (sometimes, more,) others will be leaning on you. That’s a big difference.
