Failed CSAT (Suneung)? Here's Your Recovery Plan

Pro tip: A repeat candidate registers through the high school they graduated from or through the district education office covering their address, rather than through a school. Registration for the 2027 exam runs 20 August to 3 September 2026 online at mycsat.re.kr, then 24 August to 4 September 2026 in person. Retaking has no bearing on the previous year's result, which does not transfer: universities use the score from the year you apply. A candidate voided for a prohibited item loses that year entirely and must wait for the next November.

• Believing the EBS linkage rate is 70 percent
  KICE sets it at 50 percent of items per area or subject, and the linkage is indirect: reused figures, tables, source passages, core arguments and reworked items rather than repeated questions. Planning as if 70 percent of the paper will be familiar leaves half the exam unprepared.
• Choosing an Inquiry subject purely because it is considered easy
  Standard scores depend on the population that sits the subject. Society and Culture had 239,403 candidates in the 2026 admissions-year exam and Earth Science II had 4,264. A small, self-selected, strong cohort produces a brutal grade boundary for the same raw score.
• Treating English like the relative-graded areas
  English is absolute. A raw 90 out of 100 is grade 1 whether 3 percent or 30 percent of the country reaches it, and in the 2026 admissions-year exam only 3.11 percent did. Push English to a secure grade 1 and then stop, because further English points buy nothing.
• Skipping Korean History because it carries no differentiating weight
  Not sitting Korean History voids the entire exam and cancels your score report for every other area. It is 20 items in 30 minutes and grade 1 needs 40 out of 50, which 15.23 percent of candidates reached, so the cost of securing it is small and the cost of ignoring it is total.
• Practising Mathematics without isolating the short-answer items
  Nine of the 30 Mathematics items are short-answer and entered as digits on the OMR grid, so there is no partial credit and no chance of a lucky guess. Items also carry 2, 3 or 4 points, which means the arithmetic slip on a 4-point item costs twice what a 2-point miss does.
• Rehearsing period four as three separate sittings
  It runs as one 107-minute block: Korean History from 14:50 to 15:20, papers collected and Inquiry papers distributed from 15:20 to 15:35, first Inquiry subject 15:35 to 16:05, a two-minute changeover, second Inquiry subject 16:07 to 16:37. Candidates who never rehearse the changeovers lose items to administrative confusion.
• Bringing a smartwatch, wireless earphones or a tumbler with an LED display
  KICE bans all electronic devices regardless of whether you use them, including smartwatches, smart glasses, tablets, earphones, electronic dictionaries, power banks and vapes. Anything unavoidably brought in must be surrendered before period one, and possession discovered afterwards is treated as cheating.
• Relying on a mobile identity document
  Mobile resident registration cards, mobile driving licences and mobile foreign registration cards are prohibited items on exam day and cannot be used for identity verification. Bring the physical card. Failure to verify identity means the paper is not scored and no result is issued.
• Filling in the provisional score table after a period ends
  The 2027 admission ticket carries a provisional scoring table printed on the reverse, but writing on it after a period's end bell is classified as cheating. Record answers during the session or reconstruct them after the whole exam.
• Building the whole plan around the regular track
  For the 2027 admissions year the regular track holds 68,134 of 345,717 places, 19.7 percent, while the early track holds 277,583, and 86.0 percent of early-track places are decided mainly on school records. Ignoring the early track narrows your options to a fifth of the market.
