South Korea’s College Scholastic Ability Test Mathematics—the Mathematics 영역 of the CSAT/Suneung—remains under the current common-plus-elective system for the 2027 admission cycle.
The Ministry of Education states that the 2027 CSAT will be held on 19 November 2026 and uses the same broad CSAT system currently in force. The 2027 examination is based on the 2015 revised curriculum even while Korea’s newer 2022 revised school curriculum is being phased into younger cohorts.
Common + elective Mathematics
The current Mathematics system contains a common section plus one elective route. Recent KICE answer materials identify the elective options as Probability and Statistics, Calculus, or Geometry. Candidates must therefore prepare the common Mathematics and the selected elective rather than treating all three electives as one paper.
Why the curriculum transition matters
Korea’s 2022 revised curriculum is being introduced year by year and reaches secondary Grade 3 in 2027, but the 2027 CSAT remains tied to the preceding 2015 curriculum. A BTT examination owner must therefore state the exam generation explicitly rather than inferring it from the school curriculum currently being introduced.
Preparation
- Confirm the elective route.
- Build the common Mathematics as one stable base.
- Train the elective every week rather than leaving it for late revision.
- Use KICE mock assessments and past CSAT materials to adapt to question style.
- Separate Korean-language interpretation issues from mathematical knowledge issues for international transfer students.
Use the Singapore vs Japan and Korea Mathematics crosswalk for curriculum transfer.
