Máy Tính Điểm CSAT (수능 등급 계산기)

Chuyển đổi phần trăm CSAT sang thang điểm 9 bậc (등급컷).

Overview

The Korean CSAT (수능) reports each subject on a nine-grade scale defined by fixed percentile cut-offs rather than by raw marks. Grade 1 is the top 4 percent of test takers, grade 2 the next 7 percent to a cumulative 11, then 23, 40, 60, 77, 89 and 96 percent, with grade 9 covering the bottom 4 percent.

About

Because the boundaries are proportions of the cohort, the raw score required for a given grade moves with question difficulty every year. A hard paper lowers the grade-1 cut-off and an easy one raises it, which is why year-on-year comparison of raw marks carries no information about relative performance.

The design compresses the middle of the distribution and stretches the tails: grades 4 and 5 each span twenty percentile points, while grade 1 spans four. A candidate near a boundary can move a full grade on a single question, and admissions formulas that weight grades rather than percentiles amplify that discontinuity.

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.
