How can we help?

Getting started

Chapter-wise JEE maths videos for Class 11 and 12. Each chapter is split into short video parts, with practice problems, previous-year JEE questions and notes.

Yes. Every chapter has a free 3–4 minute preview you can watch without paying or signing up. The full parts unlock when you buy the chapter.

Both. Chapters follow the Class 11 and 12 syllabus, and each one shows how much of JEE Main it carries so you can prioritise.

You can add chapters to your cart without an account. You log in or sign up with your email and a password just before you pay.

Chapters & courses

Buy chapters if you only need a few. If you need most of a class, the full course usually works out cheaper. Compare the prices on the Courses page.

Inside a chapter you own, each part unlocks after you watch most of the previous one and clear its practice set. It keeps you from skipping the bits that cost marks later.

Each chapter and course shows its access period on its page, counted from the date you buy it. You can renew early from your Profile page once it's within 30 days of expiring.

Yes. Videos adjust to your connection, and notes open right on your phone.
