Every November, South Korea virtually comes to a halt for one of the most important days of the year - The College Scholastic Ability Test (CSAT), known locally as Su-neung (수능).
The CSAT is a nationwide standardized exam that takes place once a year to determine which universities students can enter. It's often described as "the test that decides your future," and is considered one of the most high-pressure academic events in the world.
Administered by the Korea Institute for Curriculum and Evaluation, the exam covers subjects such as Korean language, mathematics, English, social studies, science, and a second foreign language. The results heavily influence admission to Korea’s top universities — and by extension, job prospects, social status, and even marriage opportunities.
