Lots of errors, pretends to an unrealistic administration
Lots of errors, pretty poor for the price - blatantly a money spinner for a dubious qualification in a pseudo-profession. The best PMs I've worked with have been light on this sort of qualification and heavy on experience and knowledge of the area they are working in -e.g IT. If you want to read something that might make a better leader / manager of projects or anything else, try agile and Scrum.
