After those two or three years, a student can go to a university/college to get even higher education (usually at the years of 19/20 until they finish). In STX, a student learns Danish, French/Spanish/German/Italian (at least one these), English, math, physics, chemistry, biology, health, Latin, nature geography, GLU (general language understanding), art/drama/media course/music (at least one of these as artistic lessons), history, psychology/philosophy, classical studies, and social studies. In HHX, HTX a student chooses some of these lessons. A student can have the lessons on an A-level (means every three years), B-level (two of the years), C-level (one of the years). In STX a student must have Danish and history at an A-level, and English at either A or B. The rest can be made up by choice, and it can be changed.
