Certificates and award-winning experiences are an objective reflection of your past four years, but in any case, they are all in the past. There is still a big difference between postgraduate study and undergraduate study. Students who can adapt well to undergraduate courses are not necessarily suitable for graduate students, and students who can't adapt well to undergraduate courses are not necessarily unsuitable for graduate students.

If it is not suitable for the initial test, you can speak in other parts of the second test. Self-introduction is only a part of the second interview, and the second interview is only a part of the whole process of postgraduate entrance examination. Only this will never drag down your whole postgraduate entrance examination.
