Is it true that studying in Britain pays 50 thousand tuition every year?

50 thousand a year is unrealistic. At least you can't get an undergraduate degree from a regular British university. At most, you can transfer to an undergraduate course after completing HND in a local college. In addition, at present, many colleges are not accredited by the Ministry of Education of China. You'd better ask Aspect what school to go to and what courses to take after graduation.

70-80% is still realistic, but it mainly depends on your own foundation. Many people have a poor foundation and studied English for many years.

As for the concerns upstairs, there are some, but they are not comprehensive. Generally, people who can afford to go abroad for undergraduate studies have a good family background and don't have to worry about returning to work. But if you want to stay in Britain, you need to work harder. The British government will not find fault to stop anyone from staying. The only determinant is one's own ability.

In addition, be careful. For most people, it is irrational to take going abroad as a springboard for future development, and the return on spending is limited.
