2. As for the college exam, I want to say that you are more attentive in class at ordinary times, you don't need to review at all, and there are basically no classes at the end of the term. At the end of the term, we don't have classes for half a month to a month, just like a holiday. There is no need to stay up late to review.

3, can't sleep at night, there should be a roommate factor, but it is also that my own ideas are too complicated and I think too much about everything. You should make it clear that they should be quiet at night, don't talk loudly, put down their thoughts and basically won't sleep (unless you have reached the point where you can't hear the keyboard sound).

The above three points are all based on your ability to be calm and treat your roommate. Be kind to them even if you are not very willing to communicate. If you are in trouble or disturbed, tell them and everyone will understand each other.

5. If you can't do the above, please move out and live by yourself; Because it's not just you, no one wants to live under the same roof with people who are hostile to each other.
