For the preparation for the math group, I suggest that freshmen should study hard and use Pei and Qiu's when preparing for the exam. It's easy to get points for the professional courses of the senior four groups, especially if you have chosen a topic or determined the future research direction of graduate students. You just need to focus on your future direction.
In fact, the topic is basically not difficult, but if you want to spend a lot of energy reading carefully, you must choose what you want to do. You can use your undergraduate textbooks as reference books. This part is not that difficult.
Pay attention to the national mathematics competition for college students;
For non-mathematics majors, first learn the high number part of the first part of the postgraduate entrance examination mathematics, which directly corresponds to all the contents of the preliminary competition and can be perfectly connected with the postgraduate entrance examination (it is a loss to learn several competitions without going to the postgraduate entrance examination); After learning math, brush Zhang Tiande. Strictly speaking, Zhang Tiande has mastered all the knowledge points and you have the ability to enter the finals. After all, there is not much knowledge; If you still have spare capacity, please brush it.
