As far as I know, there is no music department in Tsinghua University. It enrolls special students. Special students need to take the corresponding exams, and they will be given extra points after passing. Tsinghua University special students may have slightly different enrollment scores in different provinces and cities, but generally speaking, it is necessary to have enough scores.
I think your specialty is very good, and you should get extra points. Study. Now you are only a freshman, and there is still room for improvement in your senior three. Come on ~!
