Two school systems inside one estate
Queenstown puts the MOE mainstream and a British international campus within a few stops of each other. Queensway Secondary, Queenstown Secondary and New Town Secondary generate the Sec 3-4 A-Math (4049), E-Math (4048) and Pure Science work, Crescent Girls' on Tanglin Road adds autonomous-school expectations, and Tanglin Trust School on Portsdown Road runs a Sixth Form where students choose between A-Levels and the IB Diploma. A tutor who holds both an O-Level syllabus and an IB HL subject can fill a week here without leaving the estate — a combination most Singapore towns simply cannot offer, because most towns have no IB Diploma cohort in them at all.
