The division of majors can be seen as four levels. At first, it was 13 account category. This kind of division will definitely be known when you graduate from the postgraduate entrance examination. Further down, that's the bigger professional direction. The third episode is everyone. Sophomore and junior, the school will subdivide the professional direction. That's the third episode, and the last episode is a fine little direction, that is, the research direction you choose after graduate school or even after doctoral degree, so you only need to know the second level. Because of the division of the third level, it takes a long time for everyone to understand the differences after they arrive at the university.
Therefore, the division of this major category is a major category, and the subdivision of the major is what you will learn in your freshman year. Because basically after freshman year, the major of this level will be subdivided. All the students in a college will be roughly divided into 2~5 majors, depending on which direction you want to study, the school will open it. This is the most refined teaching that can be done at the undergraduate level. Some schools will hold classes, and some will always teach in large classes, so the knowledge involved may be relatively wide, but the level of knowledge is relatively shallow.
If you want. If you lay a good foundation for your future choice of major subdivision, you must make clear the relationship between major disciplines and general major directions, because some major directions are beyond your understanding. Search the corresponding information in advance to avoid entering the wrong line. Because there is a saying that men are afraid of entering the wrong line and women are afraid of marrying the wrong person. In the college entrance examination, it is impossible to get into your ideal major if you choose the wrong major.
