Flexible class hours, Hands-on training
Instructor in the videos didn't appear to know about the product and seemed to be reading a script. The information was not very deep. You need to rely on other resources in addition to the coursework to really learn the information.
I took the MOC On-Demand: 20778-Analyzing Data with Power BI Course over a period of 90 days. I didn't think the instructor in the videos really knew anything about Power BI, it seemed like she was just reading a script. In fact many times she would misread the lines and have to correct herself. The most useful part of the course was the labs, but they were not very deep. The course provided the basic information a person needs to pass, but not enough in the area of DAX functions and formulas. I ended up signing up for a pre-test that I could take over again until I felt comfortable with the questions.
