Mathematics major in Britain is a very basic subject. Every school has a department of mathematics, which has different professional classifications. It can't be explained clearly in one sentence, because each major has its own direction and its own curriculum. You must go to the website of the university of your choice, find your major and look at its curriculum. There are compulsory courses and elective courses here. I think this is the most professional answer. As far as the difficulty of specific courses is concerned, it also varies from person to person. You need good logical thinking and memory. Because mathematics is the foundation of all majors, it will be very difficult to enter the field of professional mathematics, and students engaged in this major have enough understanding.

Mathematics before British universities was very simple. Many people in China choose mathematics just to get into a good university. The reason why China students are good at mathematics is that China's high school and junior high school mathematics education is relatively profound. So China students think math is very similar. However, mathematics in British universities is very difficult, because their education is gradual, and mathematics before universities is easy. Entering the university is the real beginning of learning mathematics. The more you learn, the more difficult it becomes. On the contrary, students in China have no advantage. Mathematics in China University can't compare with mathematics in British universities. Because the mathematics in Britain is very developed and the research is very in-depth, the mathematics in our country is rather complicated. It seems that I have learned a lot, but none of them are deep or expert. But real pure mathematics is not so easy to learn.

Mathematics in Britain is well combined with practice, such as financial mathematics and actuarial science. They are all high-income industries. They are senior white-collar workers with great prospects, but they are really difficult to learn. True pure mathematics takes the road of research and is often close to mathematicians. In today's economic tide, not many people really learn this.
