There are other official rules of admission in certain top high schools. If a prestigious senior high school wants to admit 800 students a year, the admissions office ranks students’ scores from highest to lowest and then selects their first 700 students. The other 100 positions are provided to the students who do not meet the required standard, but still want to study at that school. These prospects need to pay extra school fees. A student can't perform badly in Zhongkao, if their scores are close to the required standard, they could still study in that top school if they can afford the expenses. Those who study in that high school must place a maximum of two points below the standard requirement. Usually, 0.5 points is a standard. For instance, if a student is two points below the standard requirement, they pay four times as much as the student who gets 0.5 points below the standard requirement. The admissions of the 100 students who are required to pay the school fees usually do not get the same admission letters as normal students receive, but they can still study and live with normal students in the same high school, with the same teacher.
