The total score of the middle school exam in Guangzhou typically ranges from 600 to 750 points. This score is based on a comprehensive assessment that includes various subjects such as mathematics, Chinese, English, physics, chemistry, and biology. The scoring system is designed to evaluate the academic performance of students in these key subjects, with each subject contributing to the overall score.

The reason for this scoring range is rooted in the educational system of Guangzhou, which follows the national curriculum set by the Chinese government. The curriculum emphasizes a well-rounded education, ensuring that students are proficient in both theoretical knowledge and practical skills. The exam is a crucial component of this system, as it serves as a benchmark for evaluating student performance and determining their readiness for higher education.

This average reflects the overall academic performance of students in the city. The highest possible score is 750 points, which is achieved by students who excel in all subjects. Conversely, the lowest possible score is 600 points, which is typically achieved by students who struggle in one or more subjects.

The scoring system is designed to be fair and equitable, with each subject contributing equally to the total score. This ensures that students are evaluated based on their overall academic performance rather than their strengths or weaknesses in specific subjects.
