So far, I like it. I like how the videos are in bite size pieces and the concepts are presented with a lot of visuals.
I am currently going through the concepts to get an idea and then I plan to go back and put the theory into practice with Python code.
The PCA section looks intriguing as I did learn this concept in a stats course but there was no code involved back then :( .
PCA is not easy. I didnt get too deep into that either, as of yet...the fact that the course is very interactive - requires your input - is what I think it's a very strong point. anyway, keep working at it!
