To gain admission into Zizhong No.2 High School, students typically need to score at least 580 points on the national college entrance examination, also known as the Gaokao. This score is a general guideline, and the actual requirements may vary depending on the student's academic performance, extracurricular activities, and other factors considered by the admissions committee.

The reason for this requirement is rooted in the competitive nature of Chinese education and the high standards set by Zizhong No.2 High School. According to data from the Ministry of Education, the average score for students who passed the Gaokao in 2020 was around 500 points. However, Zizhong No.2 High School is one of the top high schools in China, and it attracts a large number of highly competitive applicants. The school aims to maintain a high academic standard, which is why it sets a higher threshold for admission. Furthermore, the school's reputation and the quality of education it offers are factors that contribute to the higher admission points required.
