Hello Aspirant,

I would recommend Ayush Ghurka’s channel for handwritten notes and explanatory videos, entertaining with little jokes in between and solving doubts if someone posts it in the comment section.

There are channels like 5 Minute Engineering (Hindi), Knowledge gate, Khan academy, education4u, Easy Engineering Classes, and Gate lectures by Ravindra.

You can also check NPTEL in which the lectures are taught by IIT professors.

You can find these channels by a simple search on YouTube. Check whose teaching style suits you the most and follow them. If you don't understand any one of these or don't find their teaching interesting skip to the next you don't need to waste your time there. These are just suggestions some might be useful some might not.

Regards.
