HOW TO STUDY?

Hey this is 27tard and done with 10th syllabus. (pls don't say enjoy like as I do so a lot with IRL friends)
I want to enhance by problem solving skills so that my 11th and 12th JEE prep can go smoothly.

So, how can I do so? I try to solve IOQM and NSEJS problems but I get stuck, and finally forced to see the solution. I can't do HOTS questions. Agar aaj merese ye questions solve nahi ho rahe to kal JEE level kaise solve hoga?

**How to ensure that I am not rote learning a concept?** Like if I electrostatics and revise it after a week, I feel like I just watched the lectures like a zombie and did rote learning,

I am enrolled in Allen Lucknow for 11th and have Unacademy subscription.
