Chongqing jiangbei middle school is a senior one and does not attend classes in this department. According to the information released by official website of Chongqing Jiangbei Middle School, Siyuan Department is currently implementing a two-year international curriculum education project. During the study period of senior one and senior two, students are mainly trained in international courses and international examinations. However, in the third year of senior high school, the school stipulates that students must go back to their headquarters to study, mainly because the college entrance examination is only held in Chinese mainland, and it needs to be prepared and evaluated according to the domestic college entrance examination standards and requirements, so as to conform to the relevant national policies. At the same time, senior three students need to participate in relevant cultural classes and college entrance examination counseling to adapt to the domestic college entrance examination system and better prepare for the college entrance examination. Therefore, students from Siyuan Department of Jiangbei Middle School in Chongqing need to return to their headquarters in the third year of high school to successfully complete their high school studies and college entrance examination tasks.
