You can change your major when you are a freshman. Set your professional intention at the beginning of school, and then choose the major you want to change to across departments. Then you can basically take the exam for the major you want to change. If the course conflicts with this major, you can choose to postpone this major. Then you should study hard. There are two criteria for major transfer next semester: professional admission and professional access. The standard of professional admission depends on your credit scores in this major in the next two semesters. The standard of general professional admission is easy to achieve, and the standard of professional admission depends on the situation of the major you want to transfer. It is difficult to be hot and want to change careers, and it is easy to be unpopular. But it shouldn't be difficult for you to change your major ... If you want to improve the success rate of changing your major, you can apply for "demotion", that is, you can take classes with your younger brother and sister ... that's all you can think of for the time being. If you want more details, please give me your email address. I will send you the admission requirements of various majors on the educational administration online (maybe last year, I didn't see it this year) ~ Er, I forgot to answer your question ... 2. There are two conditions to be met, namely, the granting conditions of medical majors and the conditions for entering engineering majors; 3. There is a written test.

Each major will have a transfer quota of 30% of the professional number, depending on how many people you want to transfer; I hope it helps ~
