1, if you like mathematics, I suggest you study financial mathematics. This is not pure mathematics, but it will involve the application of finance, and the financial industry is also very popular in China.

2, employment prospects, Britain is very difficult, the financial crisis and the new prime minister came to power, the policy is very strict, it is difficult for graduates from non-EU countries to find formal jobs, you should be psychologically prepared, but if you return to China, the development prospects are still very good.

The difficulty of application mainly depends on your grades. This is only about you and your personal grades. Imperial College is good at financial mathematics and financial engineering.
