In our area, most JUCO's, are non-residential. So, no dorms, no cafeterias and meal plans, and no campus life/activities etc... So, athletes who live outside of the local area must find an apartment, and prepare or buy their own food and live as an adult off campus. It is common for upperclassmen at many four year colleges to move off-campus by their junior year. However, it is another thing for a freshman living away from home for the first time while trying to manage school and playing a sport.
And living in an apartment means no resident advisors on your hall to keep check of things, or tell you to turn the music down, or a resident director who may intercede with campus security if there is an issue. An issue at an apartment means blue lights and badges.
My son attended a JUCO and began his college life in an apartment as a 17 year old freshman who didn't turn 18 until October of that first semester. I would describe his first semester as great adjustment wise, but a bit rocky grade wise. He survived the first semester and it all worked out. However, some of his teammates didn't make it back after Christmas and I know of several other kids who didn't work out at JUCO's.
While some of those kids had issues with playing time, the main issue usually revolves around grades and attendance. Usually kids flunk because they don't study (they didn't have to in HS) or they aren't showing up for class.
The general ed requirements for an associate's degree at a JUCO are the same general ed courses required at the flagship state universities and the liberal arts private institutions. Basically, everyone's got to take freshman English, college algebra, history, a science sequence and social sciences. It's the same courses everywhere. The degree of difficulty can vary depending solely on the instructor, regardless of which type of institution.
