Thanks, nice one!
By the way, I completed the course a couple of days ago. I can say that the first three courses are really easy, beginner level, if you come from having completed the two fast.ai courses (even online, like me).
It's extremely useful as a review of the basics, though, given the fact that fast.ai courses are hands-on, while Ng's deeplearning.ai are a bit more on the theory-side (nothing impossible to understand, of course).
Will gladly pay a full month when CNN and Sequence Models will come out.
