My roommates always play silly jokes on me. What should I do with it?

If they don't study well, if you study well, you will become an alternative among them, and it is normal for them to brush. This is a common group phenomenon. If you want to change this situation, you can talk to them and make it clear. If they are still like this, then you have to be patient, and there is nothing to say. Change the dormitory; They wake up to apologize to you, and you treat them as buddies to help them improve their grades and progress. It is not recommended to make a fuss about such things at the beginning. I can see that you are a person with strong self-esteem, which will have a bad influence on your interpersonal relationship. If you really can't help it, ask the class teacher or counselor, who are rare experts in this field.
