Questions from Online Students & Parents

Questions from Online Students & Parents

That is exactly who the platform is built for. A student in Nairobi, Kuala Lumpur, or Buenos Aires receives the same preparation as a student in Dubai or Singapore. The digital course is self-paced; coaching is conducted via video. Location is irrelevant.
The RCSM is a 14-component chapter architecture that teaches every IB topic from first principles. It is the pedagogical foundation behind all 10 of Dr. Chadha's advanced mathematics textbooks, applied specifically to the IB AA curriculum. The result is genuine mathematical understanding — not exam technique.
Most IB resources — courses, tutors, coaching centres — are built backwards from marking schemes. Dr. Chadha's platform is built forwards from mathematical principles. The difference is not pedagogical preference. It is the difference between a student who recognises question types and a student who understands mathematics.
Yes — the digital course is entirely self-paced with lifetime access. Work through it in whatever sequence suits your IB schedule. There are no fixed deadlines or live sessions in the digital course. Coaching is scheduled separately to suit your time zone.
Every course purchase is covered by a 30-day guarantee — full refund, no questions asked. If within 30 days you feel the course is not right for you, write to us and we will refund in full. We are confident in the material, but we want you to feel safe making this investment.
