Is this online or in-person?

100% live online. Your child joins from home with just a laptop and internet. Every class is live with Ajay teaching in real-time. No pre-recorded videos.

What age is this for?

Ages 8–18 on a four-level ladder: Code Starter (8–10), Python Builder (11–13), Game Dev / Web + App / AI Builder tracks (13–16), Capstone (15–18). Every level starts from where the child is.

Does my child need prior coding experience?

Not at all. Level 1 and Level 2 start from absolute zero; the Level 3 tracks assume Python Builder or equivalent.

What does my child need to join?

A laptop with a stable internet connection and Zoom installed. That is it.

How is Own Sandbox different from YouTube or other platforms?

Own Sandbox provides structure, accountability, a teacher who knows your child's progress, and 16 finished projects.

What is the refund policy?

Full refund within the first 2 weeks. No questions asked.

What class timings are available?

Evening batches after school hours, 6 days a week. 1.5 hours per session.

Is this only for kids who want to become programmers?

No. Coding and AI thinking helps in any career. We teach kids to build things and think like engineers.

Questions about this course

What are the class timings?: Evening batches after school hours. KIDS and the maths/science courses run 1 hour/day (Mon–Thu); the longer coding courses run 1.5 hours/day on Monday, Wednesday and Friday. The off-days are deliberate — that is when your child builds on their own, which is where most of the real learning happens. Batches exist for Indian and international time zones; exact timings are shared at enrolment.
What if my child loses interest after a few weeks?: It's the #1 parent fear — and we designed for it. Every session ends with "show and tell" where kids demo what they built. That ownership keeps them hooked. And if it truly isn't working, you get a full refund within the first 2 weeks, no questions asked.
What is the refund policy?: Full refund within the first 2 weeks if your child decides it's not for them. No questions asked. We want kids who want to be here.
Are there instalment options?: Yes. We offer flexible instalment plans so the fee doesn't become a barrier. Contact us on WhatsApp and we'll work out a plan that suits your family.
