"입시" refers to the college entrance examination process in South Korea. It is a crucial period for high school students, as their performance on the 수능 (College Scholastic Ability Test) largely determines their admission to universities. The exam typically takes place once a year and covers various subjects, including Korean, Mathematics, and English. The preparation for 입시 often involves intense study schedules, private tutoring, and attending 학원 (cram schools). Many students feel significant pressure to succeed, as the results can impact their future career opportunities and social status. This competitive environment shapes the educational landscape in South Korea.
