First of all, you must take the GRE, and the GRE score is very important. To learn those subjects and learn the specialized courses of this major well, high GPA is king. You can choose an elective course to brush GPA. Next, I'm going to take the TOEFL, and it seems that I have to take the GMAT (Graduate Entrance Examination for Business Administration), which seems to be this. In English, this should be enough. In addition, foreign countries attach great importance to social practice and scientific research, and usually do more voluntary work, and it is best to have proof (but I despise those who are unwilling to serve others from the heart, but are very utilitarian, so it is best because you have this sense of repaying society, and I think Wuhan University students should also have this sense). Scientific and technological innovation is very important, so it is very important to do more projects or research with teachers and participate in more professional-related competitions. If these points can be done well, it is estimated that there is no problem in application.
By the way, many managers of Wuhan University are going abroad, so talk to these people more.
Originally wanted to go abroad, but due to family conditions and various factors, I had to give up, a little helpless. Come on, encourage you with the words of one of our professional buddies, as long as you want, nothing is impossible!
