That's true. The re-examination for postgraduate entrance examination is mainly composed of personal self-report, foreign language test, written test and interview. Some colleges or majors only have written tests or interviews. The interview duration is about 15-20 minutes. What did the tutor see in such a short time? No matter what you say or how you say it, the gap will come out. You know how important this is. It seems impossible to prepare, but there are rules to follow. Look at some institutions. For example, Tsinghua East Gate's seven postgraduate entrance examinations and Tsinghua Peking University's re-examination are basically done every year, which is a clear rule. In some places, the re-examination of three colleges and universities still needs to be adjusted, but it is not clear, giving students a chance. So it is also divided into places, not all of which are reliable.
