"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

"I do not teach students what to write. I teach them to understand — so deeply that no question can surprise them."— Dr. Ritukar Chadha, PhD (Maths), M.Sc (Maths)
"I had tutors and courses before. None of them taught me to think mathematically — they taught me to recognise question types. Dr. Chadha's approach is completely different."
