high school, senior high school
A school for students aged 15-18, covering grades 10-12. Short for 高等学校.
I met up with a friend from high school after a long time and talked about the old days.
My son says he wants to go to university after graduating from high school next year.
高校 is short for 高等学校 (senior high school).
