It can be said that only those things will be tested every year, and you can summarize them after reading the real questions. Duff's ordinary differential equations and discrete mathematics are famous all over the country. It is particularly worth mentioning that Duff also has a National Discrete Mathematics Center in Fujian Province, which is presided over by the president, Academician Fan Genghua. In recent years, the emerging biomathematics is also very good, led by a well-known professor, Dr. Chen Fengde from Peking University.

In a word, math exams are all about those contents, but the topics of postgraduate entrance examination pay more attention to methods and skills, so they pay more attention to problem-solving skills when they have a solid foundation. Welcome to Duff.
