Calculation method
The difference of admission line in a certain year = the average admission score line in that year-the corresponding filing control score line in that year. Taking the enrollment situation of a key university in Beijing as an example, the difference of admission line is calculated as follows:
Example: Analysis of the admission of a key university (science and engineering) in Beijing from 2003 to 2008 by simple line difference method Example: Average admission line difference = (62+70+69+69+64+58)/6 = 65;
Obviously, according to the situation in previous years, it takes an average of 65 points to apply for this university, and the highest one needs 70 points. To be on the safe side, you must leave enough insurance space in 2009 according to the size of the admission score interval and the distribution of the number of people in each score segment. Candidates are advised to leave at least 10.
