Most of the applicants for the Institute of Chemical Engineering are two books and one book. If it's 2 1 1, they'll go to summer camp and push the exemption test in previous years. If they take the postgraduate entrance examination, there are not many students in 2 1 1, so there is no undergraduate discrimination, and it depends on grades and abilities.
Admission is based on the total score of the initial test (500 points)+the total score of the second test (240 points).
Therefore, the initial test is good, and the re-examination pressure is small, but it does not mean stability. You need to keep working hard to keep your ranking in the second test.
