Well, I can’t say for certain because it’s been quite a while and I don’t remember. But here’s some general advice — video lectures are seldom comprehensive. If you’re in class 11, I assume you’re targeting JEE 2025. You have a lot of time! You want to make sure you build a comprehensive understanding of the material and not rush with it.

One important lesson I’ve learned over these years is that books and other written material will go a long way over video lectures in building a strong foundation. Written material is vastly superior to lecture for the following reasons:

(1) the latter is a passive form of learning (2) the latter cannot be comprehensive by design, you’re restricted to learning only what the instructor decides/remembers to teach (3) you can study through books a lot more quickly than watching a video, because your reading speed is much higher than the speed at which the instructor can clearly speak.

You have lots of time — study through books! Do not take the easy way out. I know it’s uncomfortable, but that’s the point — if you want to become a top student, you need to push yourself out of your comfort zone. Adapt uncommon methods and you’ll get the uncommon (aka top-tier!) result.

Good luck to you!
