Trade-offs
- !ISI rated academic and other achievements only 'Good', below the 'Excellent' personal-development grade
- !Published exam-results figures readily available are from 2019 and not confirmed current, limiting visibility of recent academic outcomes
- !Vertical city campus means limited on-site sports fields and outdoor space compared with traditional boarding schools
- !Premium international fee tiers (up to £39,105/yr plus VAT and boarding) make it a high-cost option
- !Premium fees, with DP at up to £16,033 per term inc. VAT for 2026/27 plus deposit and capital charges
- !Recent ISI inspections use a met / not-met framework, so no top graded band evidences excellence
- !Programmes split across separate campuses rather than one continuous all-through site
- !Day-only school with no boarding provision
