Downvoted for plagiarism which I suggested in your intro that you obviously did not read, or you would not repeat the plagiarism. Your post should have 20% source text maximum, this one has way over 50% copy/pasted.
If you were as educated as you stated in the intro post, then write your own material and you would fare much better in the long run.
All you are doing is making money on someone else's information this way, not good, and it won't last long.
Sorry next will try to avoid to copy resources
