The admission score in Nanjing is notably high due to a combination of factors including academic rigor, limited university capacity, and strong demand from students.

Nanjing, the capital of Jiangsu Province in eastern China, is home to several prestigious universities such as Nanjing University and Southeast University. These institutions are renowned for their academic excellence and rigorous admission processes. The high admission scores are a direct reflection of the competitive nature of these universities. According to the Ministry of Education, the average admission score for Nanjing University in 2020 was 698 out of a possible 750 points, which is significantly higher than the national average.

The limited capacity of these universities also contributes to the high admission scores. Nanjing University, for instance, has a student population of approximately 35,000, but it receives thousands of applications each year. This high demand, coupled with a fixed number of available spots, results in a highly competitive selection process. The limited number of seats means that only the most qualified candidates are admitted, thus driving up the admission scores.

Furthermore, the strong demand for education in Nanjing is influenced by the city's reputation as a hub for academic research and innovation. Nanjing has a rich history of education, with some of the oldest and most prestigious schools in China located there. This historical legacy has created a strong cultural emphasis on education, leading to a high number of students aspiring to attend these institutions. Data from the Jiangsu Provincial Department of Education shows that the number of students applying to Nanjing's universities has been steadily increasing over the past decade, further intensifying the competition for admission.

In conclusion, the high admission scores in Nanjing are a result of the academic rigor of the universities, limited university capacity, and the strong demand from students. These factors combine to create a highly competitive environment where only the most qualified candidates are admitted, leading to the high scores observed.
