Does anyone else feel this while revising for JEE/NEET?

I wanted to ask something.

Whenever I need to revise just ONE topic (for example Kirchhoff's Law, Aldehydes, Plant Hormones, etc.), I usually end up opening YouTube.

But most one-shots are 1–3 hours long, and even with timestamps it's difficult to jump exactly where I need.

Shorts/Reels are too random and not organized topic-wise.

Is there any app where I can simply search a topic and watch a 3–5 minute revision whenever I have free time?

Or am I the only one facing this?

Would you actually use something like this, or is YouTube enough for you?
