For the preparation for the math group, I suggest that freshmen should study hard and use Pei and Qiu's. 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 should choose what you want to do. You can use your undergraduate textbooks as reference books. This part is not that difficult.
By the way, the final ~ free travel, as well as 200 yuan subsidies, but I bought the subsidies directly for Russian dolls (I heard that most school finals have prizes, and there are additional subsidies, but we don't have them, so I'll spit them out here).
By the way, it is very easy to win prizes quickly, but it is a long process to sprint to the final or prepare for the postgraduate entrance examination.
Mathematical analysis and advanced algebra are the foundation of college mathematics introduction, and there are many learning resources on the Internet. What I recommend is:
1. Teacher Chen Jixiu's Mathematical Analysis
2. Teacher Qiu's Advanced Algebra
These two courses can be found on the Mile Mile. Of course, I hope you don't go there like a play.
