Trade-offs
- !Premium fees, with senior-year day tuition near GBP 40,000 and full boarding around GBP 69,000 a year at Cobham
- !IB continuum breadth (all four programmes) is concentrated at Egham, not uniform across all three campuses
- !IGCSE is not offered, so families wanting a British GCSE route are not served
- !Current ISI framework yields a 'met all standards' outcome rather than a published top graded band
- !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
