- !Split-campus model means primary and secondary siblings attend different sites
- !Very high tuition relative to most HK international schools
- !Mandatory non-refundable HK$40,000 annual capital levy on new offers
- !Multi-million-HKD debenture system that favours high-wealth and corporate families for admission priority
