This article provides an overview of the education system in Japan for a 16-year-old student. It explains that the system consists of six years of primary school, three years of middle school and three years of high school. Primary school students are taught basic subjects such as mathematics, science, language arts, social studies, music and art, while middle/highschool students learn more advanced topics such as calculus, physics, chemistry biology and foreign languages. The grade level that a student is enrolled in depends on when they began their schooling - earlier than usual means being one grade ahead; later than usual means being one grade behind.
