Postgraduate entrance examination is generally a public course proposed by the Ministry of Education and a professional course proposed by universities, but this exam is called unified examination, which refers to the unified national examination conducted at the same time according to regulations, and the unified examination is not a volume. If it is a thesis, this exam is called the joint exam. Regardless of the unified examination or the joint examination, it must conform to the national line (except for 34 self-planned colleges and universities). On the basis of the national line, the school line is determined, and the school has the right to raise the score line, but has no right to lower the score line.
