Here's the thing. After the freshman is admitted, no major will be assigned. After finishing the basic course in the same school, it will probably be one academic year later. Of course, it depends on your personal wishes and grades.

At that time, all departments will publicize, that is, recruit students. It is quite good to implement the teacher competition enrollment system now. It is not the final decision of the college entrance examination, but you can also give yourself time to familiarize yourself with your major before making a choice.
