High schools in South Korea teach students for three years, from first grade (age 15 - 17) to third grade (age 17 - 19), and students commonly graduate at age 18 or 19. High school students are commonly expected to study increasingly long hours each year moving toward graduation, to become competitive and be able to enter attractive universities, such as the top SKY (Seoul National, Korea, and Yonsei Universities). Many high school students wake and leave home in the morning at 5 a.m. and return home after studying well after 10 p.m., then return to specialty study schools often to 2 a.m., from Monday to Friday and also they often study on weekends.
