The student review system has been too slow while grading assignments.
The presenters are certainly blockchain experts and there is lots of good content but the presentation could have been much better; It was mostly a monolouge with little or no animation, slides etc. Too many times, the faculty tried to promote their blockchain book and in some of the links for additional reading, the redirection was to the Blockchain Research Insitute, with no sign of the additional reading. INSEAD is the academic partner for the course, but there is not single session by regular INSEAD faculty, you only get a certficate with an INSEAD logo.
The above is for the whole specialisation, not just this course.
