I have no books. To tell you the truth, I studied in a junior college for two years. Don't be cheated. Beijing Jianshe University was founded by the former vice president of Agricultural University. Private schools and general private university countries do not recognize academic qualifications. They are not full-time ordinary universities. They don't want college entrance examination scores, so they have money to enter school. The diplomas issued by the school are not recognized by the state, and they can only get diplomas from other famous universities through self-taught exams and successful exams. The self-study exam is also a national exam, and the system is similar to the college entrance examination, so it is difficult to get a certificate.
