The sessions were fabulous and of right length. The questions and material are thought provoking and thus I found them extremely effective. I do not see the time go by when I am working on these units. For my first on-line course, I can say that I was skeptical in the past about on-line courses, when done right, as this one is, it is an amazing experience. I really like the tone of the videos and the narrative materials. The best part with EDUZZA is that they provided a lot of customized training material and for busy professionals like me, those videos proved immensely helpful in self learning.
