One of the differences is the professors and teachers between university and high school. In college, I am required to be more responsible for my own education. Because even though we were ordered to do homework like a child. But no one came to note that we do that? Or call the parents to sue that we didn't do his homework.
College students have the most freedom and control over their education.
In college, I find my social life has changed. Since I'm away from my parents, it's easy for me to go out anytime I want especially during at night where there was no curfew at all. Back then, when I was in high school my parent doesn't allow me to go out as often as I wanted.
