In high school, the friends you make in class tend to have more entertainment and conversational purposes. In college, getting close to someone in class tends to be more of an opportunity for a mutualistic relationship. The topics covered by the professor in class can sometimes be extremely detailed. Sometimes students may not be able to get everything, but if they are lucky and found a friend in the class, they may have been able to achieve what the students were unable to achieve. Now, once they graduate from high school and enter college, friends have a deeper purpose in the classroom. That said, high school is contrasted with college because one feels like a daycare for teenagers and the other is more of a real world for young adults. In high school, teachers try to teach students how to be responsible by monitoring their attendance and making them do homework, so once they graduate and move on to college, they are more independent and prepared to succeed in higher education.
