Students preparing for JEE Mains and Advanced: Class 11, Class 12 and droppers. If you know the basics of a chapter and want to get good at solving its problems, this is for you. Olympiad aspirants have joined too.

What do I get when I join a cohort?

Live classes with Adi Bhaiya, a DPP with solutions after every class, doubt sessions on Zoom with two IIT mentors, a chapter test with a leaderboard and feedback, the recording of every class, and the cohort community. One chapter per cohort, start to finish.

What if I miss a live class?

The recording is added to your cohort page after the class. Watch it, do the DPP, and bring your doubts to the next doubt session. You are caught up.

How are doubts solved?

Two ways. During class, in the live room: type it in chat or raise your hand. Between classes, in doubt sessions on Zoom with two mentors from IIT, where you can ask by chat or unmute and talk it through.

When are the classes?

The full schedule, with dates and timings, is on the cohort page before you enrol. Every class is recorded, so a clash with school or coaching is not a dealbreaker.

No. Everything runs in the browser on a phone, tablet or laptop: the live class, recordings, DPPs and tests. Doubt sessions use Zoom.

What is the refund policy?

Full refund if you ask within 7 days of purchase and before the second live class of the cohort. Recorded courses are refundable within 48 hours of purchase.

Can I still get the first batch?

Yes. Art of Problem Solving - Mechanics is available as recordings, with every DPP and test, for ₹999.

Through Razorpay: UPI, cards or net banking. If a discount code applies to you, it shows up at checkout.
