There is no distinction between A and B. Northeastern University Qinhuangdao Branch is a school with a relatively low score.

All Class A universities are national key universities directly under the Commission of Science, Technology and Industry for National Defense or other ministries and commissions. For example, our school is one of the few 32 key universities in 1960. Before the enrollment expansion, a B was both two universities. Because of the enrollment expansion, two universities with higher scores were also upgraded to one. These schools are all local universities.

In order to improve the admission rate of candidates, the Admissions Office divides one book into two groups, A and B, but the admission scores of the two groups are the same, taking the form of separate admission. Candidates can apply for one volunteer and one school for two volunteers (even more, but useless), and at the same time, they can apply for one volunteer and one school for two volunteers in B. If a candidate is not admitted, he will be admitted voluntarily according to B. And the wishes of a and b do not affect each other. This is equivalent to a group of schools in which candidates can have two first-choice schools and two second-choice schools. Of course, the quality of the second batch of undergraduate class B schools is worse than that of the second batch of undergraduate class A schools.
