Hello @shairaalano,

The first rule you should follow on Steem is that you should always read the rules given in the right part of the community's main page. They are written below the description.

The steemitcryptoacademy community is for learning purpose only and you should not write your personal queries here.

To answer your question, about the YouTube channel, I would suggest you to go through WhiteBoardCrypto, FreeCodeCamp, DappUniversity YouTube channels.
