You can choose both of these exam subjects, and the difficulty is not much different. Otherwise, you are not allowed to make your own choices. Just take the exam at your local school, and the enrollment unit will send the professional papers you want to take to your test center. Of course, students from different majors will sit in the same examination room. Independent marking means that schools can draw retest scores according to their enrollment this year and candidates' scores. This score line is basically higher than the national line. The national line that fails to pass the school regulations is not allowed to enter the second interview. I didn't understand any of this before. When preparing for the postgraduate entrance examination, I went to Wenhai to consult a professional teacher. I suggest you consult. You will get unexpected results. You will get twice the result with half the effort when reviewing.
