If you have a problem with this unqualified roommate, then I suggest you don't worry. You should talk to other roommates first. If they all think that this roommate has the same problem as you, then you can work it out together.
First of all, you need to make sure there is something wrong with this roommate, not you. You need to make sure that everyone's point of view agrees with yours. It's best to make sure that there is nothing wrong with your way of doing things. If there is nothing wrong with your work, you are not afraid of being accused by others.
If you disagree with this unqualified roommate on some things, then you should seek other fair and just roommates to judge. However, it should be noted that roommates should not be too measured, do not deliberately crowd out and dislike her, and do not generalize. Even if a person's quality is too poor, she sometimes does one thing right, not necessarily everything she does is wrong.
If you are a girl, I suggest you be careful not to hurt others, but don't guard against others. Beware of people with no quality gossiping behind their backs and sowing dissension. Girls who have no quality often do this kind of thing, just be careful, but don't deliberately do something wrong to frame others.
If her quality is really poor and affects the normal life between your roommates, then I suggest that she can move out of this dormitory or complain to other teachers about her. If you have a deep conflict with her and she refuses to move, you can also change your dormitory.
Note that even if a person's quality is too poor, she sometimes does the right thing and can't look at her with colored glasses. If she needs any help, you can also lend her a helping hand. If she is ungrateful, don't help her next time.
