In my experience most of the time they are not. You either win the parent lottery or don't. Many college students are missing the basics. It's embarrassing, possibly confusing but true.

Colleges shouldn't cater to the bottom of the barrel. People who haven't learned basic time management, how to study, etc., after 12 years of formal education shouldn't be enrolled.

ATM I'm incredibly frustrated with worthless gen-ed classes that take up way too much of my time from working on cool and challenging things.
