Frequently Asked Questions
How does the Korean CSAT (Suneung) grading system work?
The CSAT (수능) uses a 9-grade system based on percentile rank. Grade 1 is the top 4% of test-takers, Grade 2 is the next 7% (top 11%), and so on. Each subject is graded independently. The 9-grade system replaced the previous score-based system in 2005.
What CSAT grade do I need for top Korean universities?
Top universities (SKY: Seoul National, Korea, Yonsei) typically require Grade 1–2 in major subjects. Medical schools require Grade 1 in most subjects. Regional national universities generally accept Grade 2–3. Grade requirements vary by department and admission type.
How many students take the CSAT each year?
Approximately 500,000 students take the CSAT annually in South Korea. The exam is held on a single day in mid-November, when the entire country adjusts schedules (delayed work hours, flight restrictions) to support test-takers. It covers Korean, Math, English, Korean History, and elective subjects.
