Despite the fact that the approach of the course is interesting, the offered material is not updated, and a subject like this, about seven years back in history, can have a very different face today, mainly after having a world chased by a pandemic, for more than a year now. The data used are old and as mentioned during the course, many of the positions of the countries cited in the different lists that were presented, vary considerably, and are certainly different today.
This is a very dynamic subject whose approach needs to be adjusted with time... It is absolutely necessary to update the contents of the course.
Thanks for your attention.
My best regards.-
PS. If this is ever done, I would like to have access to the updated version of the course.
