This is a poorly veiled attempt at selling the PMBOK book. To be clear, the core lessons and definitions that the course provides are perfectly fine. But it's a better use of your time and money to just buy the PMBOK thing and read it and take notes. It will be cheaper and you'll not miss anything. (1/4 of the 'course material' is telling you to read various chapters of that book anyway. And even though they say it's optional, some exam questions are over things not covered in the videos.)
The exams are based on memorization of definitions, not a real understanding of the concepts (always an indicator that the course is not meant to teach things, but to fail as few people as possible). The assignment grading system is calibrated to a point where you can only fail if you submit a completely empty document, or a Gary Larson comic strip or something. For each section of an assignment, you can mark it with 1, 7, 8, 9, or 10 points. And the definitions are such that, if the section *exists* in the delivered assignment, you can't mark it 1. So, the *minimum* you can get from each section is 7 points unless you are a complete idiot.
And make no mistake, there are a LOT of idiots taking this course. Easily 1/3 of the assignments I graded were either completely irrelevant documents. I actually saw, (and I'm not kidding) "a schematic of a control building from the Republic of Iraq Ministry of Electricity" submitted as a deliverable. The sad part is, that is the only one I could easily mark with 1 point in every section. Half of the other assignments I reviewed honestly didn't deserve to pass, but the rubric is so poorly (or actually, *intelligently* calibrated) that I ended up giving them a passing grade. Because god forbid, this course fails *anyone* who is paying €40/mo on this mediocre waste of time.
Just buy the book, and send the "teachers" a message telling them you bought it. I'm certain they will feel happier and more content knowing they managed to peddle that book to one more person.
