Undergraduates are divided into specialized courses and basic courses during their college years. Generally, there are about 24-30 courses in total, but only specialized courses of about 10 are useful. What courses are there in the university? 1. University courses are divided into compulsory courses and elective courses. Elective courses are divided into restricted elective courses and unrestricted elective courses. If divided by major, that is, public courses and professional courses, the two can cross. Compulsory courses are relative to "elective courses". From the original meaning, it is very important to explain the courses that must be studied and mastered in learning. For example, in university study, philosophy is a compulsory course; There are also some national examination courses, such as CET-4 "Oral English". Its meaning is very broad. The main required courses for undergraduates are: ideological and moral cultivation, Marxist principles, Mao Zedong theory and concepts, English, modern history of China, military theory, specialized courses and physical education. 2. Public courses are divided into public compulsory courses and public elective courses. Public compulsory courses include introduction to Mao Zedong Thought, ideological and moral cultivation, physical education class, college English, etc. Public elective courses involve various majors, and there is no limit. You can choose enough credits. 3. Professional courses are divided into professional basic courses and professional main courses. Professional basic courses focus on basic theories and basic knowledge related to majors; Specialized courses focus on professional theories and skills directly related to majors. Specialized elective courses must be selected in the subjects specified in the training plan, which is restrictive. 4. Generally, most of the courses in freshmen are public basic courses, while the courses in sophomores and juniors are professional basic courses and professional main courses. In seniors, graduation design and internship are started, and there are few courses. What courses do freshmen mainly study? Freshmen mainly study some basic courses, that is, public courses. But the major is different, and the course arrangement will be different. Common basic courses are: College Chinese, English (I) College English self-study course (I), advanced mathematics (I) Calculus, computer application foundation, basic accounting, physical education, etc. University science disciplines and their corresponding courses: civil engineering: material mechanics, structural mechanics, fluid mechanics, soil mechanics, building materials, concrete structures and steel structures, building structures, bridge structures, underground structures, road survey and design and subgrade and pavement structures, construction technology and management materials science: advanced mathematics, general physics, linear algebra, physical chemistry, analytical chemistry, organic chemistry, materials research methods, materials science foundation, Basic biotechnology of materials engineering: inorganic chemistry, organic chemistry, analytical chemistry, botany, zoology, biochemistry, microbiology, pharmacology, pharmaceutical analysis, genetics, molecular biology, cell biology, immunology, plant tissue culture, biochemical separation technology, genetic engineering, cell engineering, enzyme engineering and fermentation engineering.
