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

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.
