1, Mathematics and Applied Mathematics
Mathematics and applied mathematics are the most difficult subjects in the department of mathematics. In fact, the difficulty can be seen in the undergraduate course. The undergraduate courses cover analytic geometry, advanced algebra (specialized course 1), mathematical analysis (specialized course 2, known as enhanced calculus), abstract algebra, real variable functions and so on. If you take the postgraduate entrance examination, the difficulty is self-evident, and those who are not good at math must choose carefully.
2. Probability theory and mathematical statistics
In fact, the difficulty of this course is much better than the first one, which mainly includes the basic concepts of probability theory, random variables and their probability distribution, numerical characteristics, statistics and their probability distribution, regression analysis and probability statistics calculation with Excel. However, with so many main contents, it can be seen that the difficulty of postgraduate entrance examination can not be solved by a simple person.
3. Information and Computational Mathematics
This subject is still very good in the future employment, because it is mainly a computer major, such as data structure, computer composition principle, operating system and computer network, so the difficulty is still relatively high, but it is still very good compared with before. Those who are interested in computers can try to participate, of course, provided that your math foundation is good, otherwise it is better to be cautious.
