Learn Complete Salesforce
This is a Udemy Course https://www.udemy.com/salesforce-training/ They always have specials, I got access to the course for US$10. It seems to be quite comprehensive, and the presenter's accent will mean you need to listen closely to the videos, which is good, as you will learn something. See a YouTube video sample here https://www.youtube.com/watch?v=KJboB6H7Ado.
Blogs
There are so many new blogs out there at the moment dedicated to helping learn Salesforce from scratch. They are quite good.
