This can be challenging for students as they will have to decide what time the will take their courses and how those courses will align with other obligations.".
When one is in college he is entirely responsible for himself. The student is expected to balance his responsibilities and set priorities but in high school the student is constantly reminded by teachers and parents about responsibility and duties. Also the outcome of not doing those responsibilities are more severe in college as more is expected from the individual. Not doing a homework in high school might mean one can hand it in the next day if he makes up a reasonable excuse. However, in college he will suffer a grade penalty or maybe it will not be accepted late unless there is a real excuse with proof, like a sports event or a health/family issue. During college the student will be loaded with so much official paperwork that at some point he will not know what he is signing or what paperwork is missing in order for things to be settled. This problem gets especially frustrating if the student studies abroad. A foreign student here in the United States needs to undergo a ridiculous amount of tests, needs a lot of papers and losing one might mean serious trouble. This was not a problem in high school as living in a house with one's family meant they were responsible for this.
The amount of classes one had to attend on a normal day during high school was equivalent to around six hours a day while in college the average ranges from three to four. However, the amount of homework and material to study is very different. One hour is the average time a high school student spends on doing homework and studying a day while in college it might move up to around three hours depending on the classes one takes. The quality of the work needs to be always the best as a student cannot get away with putting in minimal effort and expecting a decent grade, like in high school.
