Trade-offs

  • !No public university-placement/matriculation data
  • !Enrolment size not disclosed publicly — hard to gauge cohort scale or community depth
  • !High fees (up to ~KRW 35.3M) with limited public outcome data to justify the premium

  • !No published IB average / externally verified academic-outcome metrics (AP results not public)
  • !Fees are high (~KRW 30–35M/year) at the upper end of the market
