It's really hard to say Some schools offer so-called "top classes" or "elite classes". They are general education, so they have more classes than ordinary freshmen. General professional courses, freshman courses are generally composed like this:

(1) Basic courses: College English 1, College English -2, Physical Education-1, Physical Education -2, Situation and Policy-1, Military Training, Military Theory, Ideological and Moral Cultivation and Legal Basis, Outline of China Modern History. Some majors include advanced mathematics-1, advanced mathematics -2, linear algebra and probability statistics.

(2) Specialized courses: Generally speaking, there will be 3-4 courses in a semester, and the whole freshman is 6-8 courses.

(3) Freshmen can't choose courses because they just entered school last semester, so there are some "elective courses" in the preset courses, which can't be returned.

Generally speaking, there are many courses in engineering and medicine, among which chemical engineering and other interdisciplinary subjects are the most, so we should learn not only basic chemistry, but also basic engineering. There are also many specialized courses such as materials, which require drawing and a lot of engineering training.

If you can determine the specific categories of literature, science, technology and medicine, I will continue to help you analyze them. Thank you.
