In my opinion, the lack of geography-specific pricing makes the evaluation (tests and assignments) and certification inaccessible to a significant population. Of course, one can audit the course anytime but it’s hard to have the same level of sincerity and commitment when there’s no incentive (certification that can probably be showcased on LinkedIN or CV) or deadline based timeline for the course.
I appreciate that these courses have been made available to anyone who wants to learn, but my point is concerning the meagre completion rate.
