I studied administration as an undergraduate. Of course, I changed my major when I was in graduate school.

At present, all the graduate students enrolled in the unified administration are masters, and no one recruits a master's degree in administration. You can rest assured of that.

At present, there are only MBA, master of accounting and master of public administration in management, but there is no master of management.

Don't worry, the master of administration belongs to the master of knowledge. If you want to apply for graduate students majoring in administration, you don't have to worry at all.
