The university is divided into classes, but when I was a freshman, because it was a public course, almost all majors would attend classes together, so everyone in the same class often stayed together and had more contact time.

After sophomore year, depending on the major or course, everyone may not have classes in the same classroom.

As for your classmates, the university will carry out activities in class, so don't worry about saying that the classmates are unfamiliar. You can even say that if there is an opportunity, you can get in touch with a professional classmate and get familiar with it.

There is also the issue of dormitory allocation, which is a matter for your college. They are usually assigned in alphabetical order, don't worry ~

There are many problems ... but I understand that I had the same mentality three years ago. Come on, kid!
