It is ok to change classes in universities, but it needs to be seen according to the specific situation. First of all, if you just change classes in the same major and don't change majors, the process is relatively simple. For example, the class you want to transfer to is in the same class as the counselor in your class. You can apply directly to the counselor as long as you agree. If the counselor is not the same, then you need to apply to two counselors at the same time, and both counselors need to agree.
On the other hand, whether you change classes or major, you need to apply to the relevant functional departments of the school.
However, it should be noted that although changing classes can make you know new classmates, the sense of existence between classes is not strong, and the familiar relationship between classmates comes more from roommates or community departments. And changing classes may not solve all the problems, because there are always people in each class who you are willing to contact and who you are unwilling to contact. So I suggest you think it over before you decide to change classes.
Time and application procedures for changing majors:
Students who change their majors are examined and approved once every academic year, and the application time is in the last two weeks of the second semester of each academic year.
At the end of the second semester of each academic year, according to the conditions of running a major, the academic affairs office will announce the number of places for professional transfer to the whole school.
In order to maintain the normal teaching order, in principle, after participating in the selection, the number of transfers in each major shall not exceed 3-5% of the enrollment in that year, and the number of transfers shall not exceed 3-5% of the enrollment in that year.
Students themselves apply to their college, fill in the application form for changing majors, and submit it to the academic affairs office after examination and approval by the college.
