Of course, to put it bluntly, college life is generally very free, your future is decided by yourself, and your study life in college is basically planned by yourself. Counselors only play a role in getting you started. Classes, studies and exams are all on your own. At the beginning, you can listen to the audition and choose the subject that you think is suitable for the teacher. In the future, as long as the teacher allows or you can arrange time, you are welcome to attend classes in other teachers, other majors and other schools.
