The scores of all subjects in Heyuan junior high school are not publicly available. This is due to the sensitive nature of student data, which is typically protected by privacy laws and school policies. Without access to the school's internal records or a specific dataset, it is impossible to provide the scores for all subjects. Educational institutions often maintain confidentiality regarding individual student performance to ensure privacy and to prevent potential misuse of the data.

Data privacy is a significant concern in the United States, as outlined by the Family Educational Rights and Privacy Act (FERPA). This act grants students and their parents the right to access and control their educational records, including grades and test scores. Schools are required to obtain written consent from students or their parents before disclosing such information to third parties. Therefore, the scores of all subjects in Heyuan junior high school are not accessible to the public without proper authorization.

Additionally, the lack of standardized data collection and reporting across different schools and districts makes it challenging to aggregate and analyze subject scores on a broader scale. While some districts may publish aggregate data on their websites, these figures typically do not include individual student scores. Instead, they provide general trends or averages, which do not offer a detailed breakdown of subject performance.

In conclusion, the scores of all subjects in Heyuan junior high school are not available due to privacy concerns and the absence of a standardized data collection system.
