Since the national unified examination of pedagogy, psychology, history, computer and other disciplines began, it seems to have brought good news to candidates. The unified examination syllabus, national unified proposition, open and transparent proposition and marking process by the Ministry of Education have brought great confidence and courage to candidates, especially those who cross schools and majors. However, as a result, more and more candidates choose the unified examination major, and the number of cross-majors is increasing year by year, so the pressure of postgraduate entrance examination is increasing. Coupled with the particularity of computer, psychology and other majors, the market prospect is promising, so it has been heating up in recent years.

Facing the ardent hopes of the students, in order to realize the candidates' dream of taking the postgraduate entrance examination, various professional courses are taught by tutors.

The structure has been established. However, these unified examination subjects are not as popular as public courses such as English and politics, so most of the make-up classes are concentrated in first-tier cities such as Beijing, and there are only a handful of truly authoritative counseling institutions.

Under this background, under the joint initiative of experts and professors from Peking University, Beijing Normal University and China Academy of Sciences, Diligence Education was established in Beijing, and it is committed to becoming a flagship brand in the field of professional course counseling and an important base for the national postgraduate training market.
