In college if you don't make studying and homework your number one priority, then you will struggle. Another thing about homework is that in high school your teachers wouldn't mind accepting late homework, but in college if you don't turn in your work on time points will be deducted or not even accepted. In college you are told to study at least two hours for each class every day, which is much more than in high school. However, I believe it is necessary because my classes are much harder than in high school. Another thing that can be said about the level of severity is the behavior of students in college compared to those in high school. In my experience, students in my high school classes tended to be much more talkative and disruptive than in the college classes I'm taking right now. I believe this is because all college students have invested a good amount of money into their education, which leads them to take it more seriously than high.
