Hey Aditya,

Hope you are doing well!

Well dear no educational source is sufficient till you have got your basics clear and have done vigorous practise ,

If you are confuse about any educational source for your preparations then complete a module and try solving the JEE mains previous year papers,If you completely solve it on your own then that's great you can go for it.

Hope This was helpful!

All the best!

Keep Smiling :)
