The University of Mining and Technology has long banned double degrees, so I can only minor in other majors. . . Minors are generally courses of management college, or law of grammar college, English of foreign languages college and so on. . . The minor is usually two or two and a half years, and the courses are different in different periods. You will get a minor certificate after you have passed all the courses you have studied. . . This certificate is on the same level as Jiangsu's college diploma, but many provinces in Jiangsu do not recognize it. . .
