For those who read her book and did the course, is there anything in the course that isn't covered by the book? what's the advantage of the course over the book?
As a side note, I have found that the most powerful technique for me is recalling.
If you just wanted the information, you could stick with the book since it goes into greater depth about the learning method.
The one thing I really like about the course were the interviews where the interviewees (such as Cal Newport and the 1 year MIT degree guy) went into great depth on their focus methods.
I also liked the assignments since the scorers gave helpful feedback although I don't know what it's like now with the changes coursera has gone through since I took this class.
