The study content of senior one last semester is not limited to compulsory one, but also includes other subjects. In addition to compulsory one, senior one had to study other compulsory subjects last semester, such as mathematics, English, physics, chemistry and so on. These subjects are all important subjects in senior high school, and students should master them comprehensively. In the school's teaching plan and curriculum, there will also be elective courses or learning content beyond their balance. Compulsory one, as the key content of senior one, is the basis of follow-up study, which does not mean that senior one only studied compulsory one last semester.
