The three universities mainly refer to "independent colleges and universities" and are "public and private" universities. At present, most provinces have cancelled the enrollment of three colleges and universities, so now all three colleges and universities have become independent institutions. Compared with a university, there is no essential difference between the two universities, and the academic system is four years. However, the tuition fees of three universities are relatively expensive, generally ranging from 1000 to 30000, while the tuition fees of one university and two universities are generally around 5000 to 6000. Usually it is several times the tuition fee of one or two universities.

There are great differences between junior colleges and undergraduate schools. There is no degree certificate in junior college, only a diploma. And the academic system is three years. If there are students who have been promoted to undergraduate courses, their diplomas will be different from those of ordinary undergraduate courses. The graduation certificate will indicate the words "the starting point of the specialty is undergraduate".

Some provinces don't have three books, and basically two books and three books are merged, but there are still several provinces with three books.

The cancellation of three books has no effect on the current college entrance examination students. If it is a province that cancelled three books on 20 18, there are no candidates who really have three books at the time of registration on 202 1. This is for freshmen in senior high school. These two candidates need not worry too much. If they want to apply, they can still apply.
