I have always learned best when I am learning on my own rather than at school or in a class environment, bar a few exceptions.
These days we can count ourselves incredibly lucky to have YouTube and other video sites where we can access an incredible wealth of knowledge for free or at low cost.
Since YouTube gets annoying pretty quickly with ads, you can use an ad blocker or just pay for premium. Youtube Premium is cheaper in India, Argentina and Turkey especially.
I’ll keep adding to these as I discover them, and if you have any suggestions just leave a comment at the end.
