There is a certain proportion limit on the proportion of postgraduate re-examination in the School of Education of East China Normal University. The specific proportion depends on different years and enrollment plans, and is determined according to the total number of enrollment plans. In the postgraduate re-examination, the school will evaluate the applicant according to the initial test results, academic background and comprehensive quality. Setting the proportion of re-examination is to ensure the quality and fairness of re-examination, so as to ensure that the graduate students who are finally admitted have high academic literacy and comprehensive ability. Therefore, although the specific re-examination ratio is different, the school will generally set the ratio reasonably according to the actual situation and enrollment plan to ensure the quality and fairness of the re-examination.
