First of all, it is very troublesome to change classes among different counselors. Generally speaking, the school will not agree, because your student number has been generated, and your student number contains your class code. If you want to change classes, the academic affairs office needs to modify the educational information you have compiled, and your student ID card and campus card also need to be replaced, which is very troublesome, so the academic affairs office of the school will not agree.

However, if you feel unfamiliar with other students in your roommate, and there are spare beds in the dormitory where other students in your class are located, you can apply to the counselor or dormitory administrator for a change of dormitory. If the reason is reasonable, it is generally acceptable.

I hope my answer can help you and make you satisfied.
