Fabio De Matos completed this course, spending 3 hours a week on it and found the course difficulty to be easy.
Although the title easily catches the eye, its goal and contents are much broader than you'd guess. It was really mind opening, since I've been long focusing on the rational way of thinking and it helped me to tap into other ways of dealing with life/world/you name it.
It was the first MOOC I took, and it really inspired me to enroll in other MOOCs that fulfull my interests. I'm told there will be an advanced session soon, and I'm looking forward to it.
