The choice of information science is relatively large. The first is advanced mathematics. You can choose A or B, which should be published by Peking University Press. A is more difficult, close to several schools and use mathematical analysis. B It is relatively simple and close to reality, using advanced mathematics from Jong Li and Zhou Jianying. And the score is three semesters, and the high score is two semesters. There is also line generation, you can choose A or B, and you should use Advanced Algebra (the textbook of A) or Linear Algebra written by Mr. Qiu. Then there is mechanics, or you can choose A or B, take a separate course with the College of Physics or the College of Arts, and use the mechanics written by Teacher Shu Yousheng. There is also an introduction to information science and technology. This course seems to be based on introduction, and the teaching materials are not clear. There is a book, Computer Culture, which seems to be a recommended course for freshmen. Then there is the introduction to calculation, which should be c++ programming. Other courses are miscellaneous, such as politics (ideological or historical outline), military theory, and English (the starting level is determined according to the graded entrance examination). . . .
