It's easy to change your major, as long as you keep telling yourself that I want to change my major, I want to change my major, and then try to prepare for the exam that you want to change your major. Liberal arts (such as law, English, Chinese, etc. ) Chinese and English, while science (such as chemistry, biology, etc. ) test English and math. Economics is to test math and English. Many people in Xiamen University change their majors every year. There are not many students enrolled in each major. Moreover, Xiamen University students are excellent, and it is not easy to successfully transfer to another department. Every year, schools can transfer to different departments. In 2006, Xiamen University still had economics, even the hottest accounting and finance, but in 2007, these departments could not be transferred. The official statement is that these departments are too hot to operate. . .
In fact, Xiamen University can also take a double degree. I suggest that if you can't transfer, you should take a double degree from your freshman year. If you can turn it, you can turn it again and return it. I believe this is more conducive to your development.
PS, I'm a successful student of Xiamen University. I hope I can help you.
Physics is not bad, but not particularly good.
