It is easy for a general correspondence college to get a diploma of management major. Guilin University of Technology and Guangxi Normal University are both good schools, among which Guangxi Normal University is easier to be admitted. You have been away from school for several years. I suggest you register through the education correspondence station of Guangxi University. They cooperate with the school to provide free pre-test counseling, and the chances of being admitted after counseling will be much greater. I signed up with them, and the tuition fee was paid to the school by myself, which was very safe. It is not easy to type so many words. I hope you can adopt it.
