Hello aspirant,

Switching to youtube to study is a good option but there are no such youtuber who can teach you all the three subjects of JEE mains, the best way is to study from books and if some doubts arises look for its solutions on internet and youtube, but just not sticking around watching videos of different youtubers and trying to do what they are saying. you know yourself the best and only you can help yourself no youtube channel ever will give you as much information as it is available with the books you have, for JEE mains just be thorough with NCERT syllabus and concepts and you will be able to do well.

I hope this helps.
