Provincial control line: the full name is "minimum admission control score line", also called blocking line and provincial fixed line. Generally speaking, it refers to the minimum admission control scores of the corresponding undergraduate and specialist batches designated by the provinces (autonomous regions and municipalities) during the college entrance examination. ?

The provincial control line refers to the lowest score (total score) standard for recruiting new students determined by the provincial admissions department according to the scores of all local candidates in the college entrance examination and the enrollment plan issued by the state. Only candidates (usually referred to as "online candidates") whose total college entrance examination scores (including the professional scores of art and physical education candidates) reach or exceed this score line are eligible to be admitted to the admissions institutions and choose to be admitted.

Average score of admission: it is the embodiment of the average level of candidates entering colleges and universities in that year. Compared with the average score of several years, if the candidate can be in this position, there is a great possibility that the candidate will be admitted.

It can be said that using the average score can avoid the influence of "big and small years". Therefore, when we use the fractional line, we should combine the highest score, the lowest score and the average score, and pay special attention to the significance of the average score.
