In the United States, the number of points required to gain admission into a high school can vary significantly depending on the specific school and the criteria used for admission. Generally, high schools use a combination of standardized test scores, grades, extracurricular activities, and other factors to determine eligibility. For Xuyi, a typical high school admission point range might be between 200 and 300 points.

The reason for this range is multifaceted. Firstly, the grading system in the United States often includes a weighted GPA, where advanced courses are given more points. For example, an 'A' in an honors course might be worth 4.5 points, while an 'A' in a regular course might be worth 4 points. This means that students who excel in challenging courses can potentially achieve higher points.

Secondly, standardized test scores such as the SAT or ACT are often a significant component of the admission process. A high score on these tests can add substantial points to a student's application. For instance, a score of 1300 on the SAT might contribute 50 points, while a score of 1500 might contribute 75 points.

Additionally, extracurricular activities and community service can also impact a student's admission points. Schools may assign points for leadership roles, consistent participation, or significant contributions to the school or community. For example, a student who is captain of the basketball team or president of the student council might receive 20 to 30 points for their extracurricular involvement.

Data from the National Center for Education Statistics (NCES) indicates that the average GPA for high school graduates in the United States is around 3.0. However, many competitive high schools, including those in Xuyi, may require a GPA of 3.5 or higher to be competitive. Furthermore, the average SAT score for high school graduates is around 1050, but scores above 1200 are often considered more competitive.

In conclusion, the number of points required to gain admission into a high school like Xuyi can range from 200 to 300, depending on a student's GPA, standardized test scores, and extracurricular activities. This range reflects the diverse criteria used by schools to assess the overall academic and extracurricular strengths of applicants.
