The course is excellent. Great quality of supplied material, teachers and assignments. I rate it on the fact that I was able to follow it and learn quite a lot on a subject that is far from easy, and I'm pleased with the results.
The only issue / recommendation I can point out : The course is not very specific on the needed background. As an example, I took this course being an engineer with a decent understanding of maths, a less-decent understanding of physics (almost no quantum physics background), and experience with python programming: in my case, it required a lot of effort in order to follow some of the chapters (specially the ones focused in quantum physics), and normally always more than the normal 8 hs/week. I recommend the student to have some background on probability theory / functions and python programming so as to follow easier, and expect some difficulty in fully understanding some of the subjects. I still rate it 5 stars.
