According to the results of the college entrance examination, they are divided into the first batch, corresponding to one institution. The second batch corresponds to two universities. The third batch corresponds to three universities. In fact, one, two and three books are all undergraduate institutions with a four-year academic system, and they can all obtain nationally recognized academic qualifications after graduation.
But it is slightly different in the scope of running a school. One is public, the other is mostly public, and there are a few private classes. Three books are generally independent institutions and so on. That is, public and private assistance.
