About 30 per cent of university students are not satisfied with their majors. It is not easy for students to change majors in universities. Some students turn to other majors in postgraduate education or quit university to participate in the college entrance exam again. Students and their parents know little about the major they select and make the wrong decision. Parents only care for the college entrance exam scores of their children and the reputation of university they apply. They neglect the factor of major and their children's interest, reports Gmw.cn
