During the undergraduate study in domestic universities, you can generally choose at most two majors. There is only one major, and the major you choose depends on which major you are interested in. The specific situation is, first of all, you have to choose one of your majors, which entered through the college entrance examination, and you can only get a diploma if you enter the university and get the corresponding credits. The other is a minor (usually in my sophomore year, I choose one of the minor majors offered by the school, and after a certain selection test, I can start studying, complete the credits stipulated before graduation, and get a bachelor's degree through thesis defense), plus a professional degree, which is called a double degree. However, some universities can change their majors in the next semester or sophomore year, but you can only enter if you meet the requirements of changing departments. ?

About elective courses. University elective courses can be divided into two categories: public elective courses and professional elective courses. Public elective courses generally require low credits, about 10 credits, and some schools have restrictions on humanities and science and technology courses that contain several credits. Professional elective courses are generally only provided to students of this major, and most of them are professional courses, with a total credit requirement of more than 20 points, which is an important way to master professional knowledge. The credit requirements of elective courses are generally hard indicators for graduation, and only after completing credits can you qualify for graduation. Tuition in some schools is related to the academic performance of elective courses.

College courses are relatively loose, so you can take more courses, but you should look at your energy. Pay attention to the time between elective courses. Some majors require certain courses. Please pay attention to the curriculum of this major.

Of course, if the courses offered by the school are not ideal, you can also spend money to study your favorite major. I wish you a good future in college.
