Just wanted to say that this course is SO SO GOOD!! FINALLY I can grasp those fundamentals, very well explained and visualized. I watch this version of the course (4.x) and the new 5.2 LTS version as they model different things and that is like a double bonus for me :-)
One reason I still like going through even beginner courses is because even on the same topic, things will get explained or demonstrated in a different way than I had heard before. Sometimes I'll even see a use or tool used that I've not seen or thought about much.
