高中, or "senior high school," is an educational institution in China that typically serves students aged 15 to 18. It is the final stage of compulsory education and prepares students for higher education, such as universities. The curriculum includes a variety of subjects, including mathematics, science, literature, and foreign languages. Students in 高中 often take the Gaokao, a national college entrance examination, which plays a crucial role in determining their future academic opportunities. High school life also emphasizes extracurricular activities, such as sports and clubs, fostering personal development and social skills among students.
