I think this method has advantages and disadvantages. First of all, in this way, people can know the real situation of the exam, understand the various problems of the candidates, and pay more attention to the various problems of failing the exam, which is conducive to the self-comparison of other candidates and improve the pass rate. But one thing can't be known to the candidates, or consult the candidates before the live broadcast, otherwise it will bring more pressure to the candidates and lead to an increase in the failure rate. Will this live broadcast help?
