"IB AA HL is one of the hardest pre-university mathematics courses in the world. Every student who takes it deserves a mathematician — not a workaround."— Dr. Ritukar Chadha, PhD (Maths), M.Sc (Maths) · Founder, R. Chadha IB Maths
Singapore is home to some of the highest-achieving IB cohorts globally. Students here are extraordinarily motivated and frequently target Oxford, Cambridge, Imperial, NUS, and top US universities. The mathematical bar is exceptional — and the preparation must match it.
