Questions parents ask
Is it really free?
Yes. The masterclass is free and doesn't ask for payment details.
Is this a live class?
No. It's a class Bhanu recorded, built so the video stops for your child's answers. Our courses are live and taught by qualified Bhanzu teachers.
Who teaches the courses?
A qualified Bhanzu teacher teaches every live class, with at most 6 students in a batch. Bhanu's recorded masterclass is your child's introduction.
How much do the courses cost?
Your Bhanzu coach will take you through the fees and help you get started, by phone, WhatsApp, email or video call, whichever suits you.
Is this a test of my child?
No. The sums are meant to be hard before the class, so a low first score is fine. We don't compare your child with other children.
How long does it take?
About 15 minutes. If you have to stop, it picks up where you left off on the same device.
