Generally, the retest difference of popular postgraduate colleges is between 1: 1.5 and 1:2, which means the elimination rate may be one-third or one-half.

Some colleges and universities will implement an equal retest. If candidates from these institutions can enter the second interview, the postgraduate entrance examination will be basically stable. But this is only for individual colleges and universities, and most colleges and universities will implement the difference retest.

The difference retest is to let more people take part in the retest on the basis of planned enrollment, and then select from a fixed number of people. The minimum difference elimination ratio stipulated by the Ministry of Education is 1: 1.2, and universities with sufficient students can increase it appropriately. Generally, the retest ratio of the difference is 1: 1.2 or 1: 6558.
