Why is the quality of education in the capital high and the college entrance examination score so low?

This question is unreasonable from the perspective of fairness, but there is never anything absolutely fair under the sun. Whether you admit it or not, the difference in education level among provinces is objective. Because the test papers are different, it is meaningless to discuss the score line. Therefore, only the scores of the national unified examination papers are discussed here, so that they can be compared. When I took the college entrance examination, there were no papers anywhere at that time, and the admission scores of different provinces were different, such as Zhejiang, Hubei, Fujian and other provinces with high scores, and some provinces with low scores. There is a simple reason. The determination of this score line is actually based on the proportion of candidates and admissions in this province, so it is not difficult to understand why the admission scores of different provinces are different, which is also based on this ratio. There are indeed reasons for national conditions. For example, the score of Hainan is very low (so many students immigrate to Hainan every year). This is to give more Hainanese the opportunity to receive higher education, and then a considerable number of them will return to Hainan to participate in local construction. If there are scores all over the country, it will inevitably lead to few college students in Hainan, and the possibility of college students from other provinces going to Hainan after graduation is definitely smaller than that of Hainan people. In the long run, it will form a vicious circle and widen the gap between the east and the west. By the same token, after unifying the scores, candidates from other provinces in China will also flood into densely populated areas such as Beijing and Shanghai. In the long run, a large number of high school students in Beijing and Shanghai will lose the opportunity to go to college, resulting in employment pressure for a large number of social youth. In short, this is due to the national conditions. Even abroad, they enjoy the same privileges. Of course, they don't all show differences in scores. For example, some famous universities in the United States need two senators as a guarantee in addition to their scores. What is this?
