Second, the most important thing in college is to study. Everything should make way for study. A full college life must be more tiring than senior three. Whether you like it or not, don't fail! No matter any subject, if you want to continue your studies, you'd better keep your credit above 3.5 points (or your average score is at most 5 points lower than the full mark, and at worst it can't be lower than 8 points).
Third, roommates are not friends.
It is not necessarily your roommate who is with you. There is a saying: "Birds of a feather flock together", and people who play well will be like-minded. Some students get along very awkwardly in the dormitory. Dormitories are just places to sleep, and some things cannot be changed. The one who gives you the warmest is also the one who hurts you the most.
