First of all, let's talk about virtual ranking. How to say that the mathematics department of Zhejiang University can also enter the top three in China, but this has little to do with undergraduate teaching, so it has little reference significance. Then there is the specific situation. The Mathematics Department of Zhejiang University has three directions, namely statistics, mathematics and applied mathematics, and information and computational science. Finally, many people think it is a computer, but it is actually mathematics. It used to be called computational mathematics, and now the head of the Department of Mathematics of Zhejiang University is this major. There are also A Qiu Chengtong classes in the Department of Mathematics, but there are only fifteen places to be evaluated every year. Qiu Chengtong used to have classes with them, but now Qiu Chengtong has gone to Tsinghua, but this influence cannot be said to be particularly great. After all, there are still many good teachers.

In terms of teachers, this cannot be considered from the perspective of high school. Every teacher's research direction is different. Teaching with research is not necessarily intense, and good teaching is not necessarily fruitful. But on the whole, according to my own personal experience, the math teachers in Zhejiang University (other teachers also have this advantage) are still very free. Although Zhejiang University has a heavy scientific research task, they are free, which is also an important reason why Zhejiang University's salary is extremely low (the lowest in colleges and universities in the province) and teachers are willing to stay. Mathematics emphasizes freedom of thought and originality, which can be satisfied by teachers with personality in Zhejiang University, provided that you communicate with them more. Many of these teachers can be regarded as people with great weight in the academic field, so teachers don't have to worry.

In fact, more than half of our school is engaged in graduate students, and the proportion of going abroad is quite high, at least 10% (I remember that in recent years, it was all top 100, top50 and so on, and it was worse to stay in Zhejiang University). Anyway, the undergraduate students in the department of mathematics basically don't expect to have a good job, but the postgraduate entrance examination is very different. I suggest you go abroad because the level of science in China is generally low. Of course, if you want to transfer to engineering, you can also consider studying in China.

Having said that, in fact, if you really go to college, you will find that these questions are often of little use. The key is your performance in college (you will understand this when you go to college).

Moreover, the first year of Zhejiang University is not divided into majors, and there will be pre-confirmation in the freshman year and formal confirmation in the sophomore year. It can be said that this is the second college entrance examination, because there are many people who apply for the department of mathematics, and they have to be in front of the college 100 to be sure to enter the department of mathematics (like statistics, the requirements are higher), so they still need to work hard after entering the university.

That's all. I hope it works for you. Good luck.
