When volunteering for the college entrance examination, you must be a minority and you can enter the minority preparatory class. This is a special form of running a school to train talents for minority areas, which is good news for minority students. If you fail in the college entrance examination and are not admitted to the key university you want to enter, but you don't want to repeat it, you can also enter the preparatory class of the school and enter the university you want to go to, just one year longer than others.
After the college entrance examination, the school will generally send a volunteer book to fill in the university, which contains some details about the enrollment of preparatory students. Some universities have professional restrictions on preparatory students. If you are a pre-college student in this university, you can only choose from the majors provided by the school after passing the exam in the next year. In case none of them are your favorite major, it will be very unfavorable.
This is also some limitations of preppie students. However, you can also choose to change majors or departments in your sophomore year, depending on how your university stipulates.
On the question of filling in the major, if you have decided to go to the preparatory course, and the college entrance examination score is close to the admission score of our school, then when choosing the preparatory course major, you'd better fill in the major that you can't get into. Don't choose a major to adjust, choose a major to adjust, which will easily get you assigned to some bad majors in the school and affect your future employment.
