1, admission line difference = average score of university admission-admission batch line (average score of university admission = admission batch line+admission line difference).
2. The difference between the admission scores is equal to the average college admission score minus the admission batch scores (one line, two lines and three lines), which means that the average college admission score exceeds one, two and three books.
Extended data:
1, line difference is an extremely important concept introduced in the simulation of voluntary reporting. Line difference can be divided into examinee's score difference and college admission score difference.
2. The score difference of candidates refers to the difference between the score or estimated score of candidates and the score of running-through control in the provinces and cities where candidates are located, that is, how many points the score of candidates is higher than running-through control.
3. The difference of college admission scores refers to the difference between the admission scores of a batch of colleges and universities in a certain province and city and the filing control scores of that province and city, that is, how many points the college admission scores are higher than the filing control scores.
4. The line difference function is mainly used to analyze and compare the admission scores of colleges and universities, especially in different years, because the admission scores of many colleges and universities often change greatly in different years, but their admission line differences generally do not fluctuate too much.
5. The calculation formula is: examinee score-filing control score = line difference. Some schools have a certain regularity in the annual admission difference (one difference and two differences)-almost unchanged. Reasonable application of this rule in applying for the exam can help us quickly lock in the ideal institutions.
6. The concept of line difference in "line difference method" is divided into two points. One is the line difference of candidates' scores, which refers to the difference between candidates' college entrance examination scores this year and the corresponding batch scores. Second, the difference in college admission scores refers to the difference between the admission scores of colleges and universities in the past enrollment year and the corresponding batch scores of that year.
7. The difference between the average admission scores of colleges and universities and the corresponding batch scores of the current year is regarded as the difference between the admission scores of colleges and universities in the Guidelines for Filling in Volunteers.
