However, if the candidates' initial test scores are not online, everything will return to zero, and the written test scores of the initial test and retest account for a large proportion of the total scores.
The key to postgraduate entrance examination is self-confidence and diligence, which are indispensable. No matter which school you apply for, the role of the tutor is limited, and whether you can be admitted is basically determined by the admissions office according to the score ranking.
