Nice test. Good test of library and information in Beijing Union University. Candidates should be clear that there is no absolute evaluation standard for graduate students of any major. A major that suits others may not suit you. Candidates need to make a comprehensive analysis of the library and information quality and future development direction of Beijing Union University (professional degree) in combination with their undergraduate majors, hobbies and future development plans, treat and take seriously the choice of postgraduate entrance examination majors rationally, and don't make hasty decisions because of impulsive or blind listening to other people's opinions, which is often very painful in the preparation process.
