CSAT D-day & Cutoff Guide

5 steps: schedule · subject · cutoff reading · grade prediction · study plan.

1. Included schedule

  • 2027 CSAT — Nov 19, 2026 (Thu). For current seniors (class of 2027).
  • 2028 CSAT — Nov 18, 2027 (Thu). For current juniors.
  • KICE mocks — June & September. Closest indicator of real-CSAT difficulty.
  • Local OE mocks — March (Seoul), July (Incheon), October (Seoul) — rotating organizers.

2. Reading the D-day card

The large number is days until the 2027 CSAT (Nov 19, 2026). The phase schedule below walks through application, test, and score-report dates; unannounced phases show an "Est." badge.

3. Subject tabs

Korean / Math are relative (9-grade), English / History are absolute (fixed bands). Inquiry (Social / Science) shows raw-score cutoffs averaged across popular electives.

4. Cutoff chart & table

  • Chart: Grade-1 cutoff trend. Your score overlays as a gold dashed line.
  • Table: grades 1-8. Latest year highlights your predicted band.
  • Korean / Math cuts swing year-to-year — anchor on the 3-yr rolling mean.

5. Predicted grade & percentile

Enter your raw score; the tool maps it to the most-recent (2025) cutoffs to predict your grade. Percentile uses standard relative-grading thresholds (top 4% = G1, 11% = G2, 23% = G3, etc.).

6. Stage-based study plan

  1. D-365 ~ D-50 (Foundation) — 7-year past exams x2, concept single-book, EBS link-book 2 passes, fixed 7h sleep.
  2. D-50 ~ D-8 (Simulation) — Weekly 3 timed mocks + error-log loop; align wake-up / meal times with test schedule.
  3. D-7 ~ D-DAY (Taper) — No new problems — revisit notes only; bed at 22:00 on D-1; light breakfast.

7. Sources & caveats

  • KICE (Korea Institute for Curriculum and Evaluation) CSAT press releases & std-score tables
  • Seoul / Incheon Offices of Education mock-exam postings
  • EBSi / Megastudy / ETOOS private-institute projected cutoffs (2021-2025)

This is a raw-score estimate. Official CSAT uses the standardized score + percentile + grade triple. For precise positioning, cross-check the KICE score-report plus a private-institute placement chart.

8. Shareable URL

Exam + subject + score are encoded in the query string — sharing the URL opens the same view.
