1, the control scores of colleges and universities admitted in advance are relatively small, mainly some schools and majors with special requirements, including undergraduate and junior colleges. The scores are determined according to a certain proportion of planned enrollment and the number of applicants.

Some colleges and universities are not satisfied with the admission of professional online students, so they can lower their scores appropriately and ask for admission. Because this part of the population is relatively small, sometimes the scores are not published in the society.

2. The control score line of the first batch of institutions is also called the key line, because the first batch of institutions are mainly national key universities, so it is also called the key line. According to the regulations, the ratio of the planned enrollment to the number of candidates is determined: 1: 1 or 2.

The scores are divided into three categories: literature, science and foreign languages. Considering the factors such as volunteering to fill in the report, the determination of the score is not mechanical, and the role of various factors should be considered.

3. The control scores of the second batch of admission institutions are also called undergraduate lines, mainly ordinary undergraduate institutions, so the control scores delineated are also called undergraduate lines, which are generally determined by slightly more than planned enrollment.

The calculation method is to calculate from the first batch of control scores, including the first batch of remainder, until the number of people has a certain margin compared with the second batch of planned enrollment, and this score is the control score. The general principle is to also consider factors such as volunteering in different disciplines.

4. The third batch of admission institutions are mainly specialized courses in junior colleges, undergraduate colleges and higher vocational colleges. Its admission score line is the admission bottom line mentioned above, also called the minimum control score line.
