Ayse N. is taking this course right now and found the course difficulty to be very hard.
I think the idea for the course is great. But I found the way they teach hard to follow. Just from the start, there are many questions that require prior understanding of Statistics, and the answers are not explained well. The content, as much as I have seen, is not very accessible.
Also for those who consider auditing this course; some videos are not available at all, so this course is not ideal for those who want to take it for free.
