"Full-time" is a common form of high school education, which means that students receive education at school according to a fixed school timetable every day. In contrast, part-time education is more flexible, and students can arrange their studies according to their own time.
In China, full-time high schools usually last for three years. Students need to complete the courses prescribed by the state, take various exams, and finally enter universities or other higher education institutions according to the results of the college entrance examination.
