Like others have shared it is difficult to follow with 2 presenters, only one of which you can see who disagree on the approach. They also did not follow their own rules or best practices. This was more of a do as we say training. The lack of attention to details was disappointing. Based on this experience I will not be paying money for any other trainings. Disappointing.

Thank you for putting this together. Marco was doing a fine job explaining. However when I got to the part (in Calculated Columns) and an off camera audio starts to argue / debate with Marco, I quit. Totally jarring and unprofessional. Sorry, but that is not how video presentations are made. Example, watch the news. You will NEVER hear the broadcast manager yelling off camera to the news anchor. There is a reason for that. It's crap. Pick the talking head. Stick with it. You will do fine. Sorry guys. Love your books. I don't like your videos.

Concepts are explain technically and how they behave, how using different things for example sumx or calculate can result into similar calculation, these things are really useful to know. In addition to this, I believe putting a use case or scenario showing when one will use one technique against other will of great use. I am learning all behavior of different technique but there is only question in my mind why i am learning different ways of calculating same things, only if there are examples which showing when one thing will be use against other will be of great use. I am happy discuss things in more details.

• – This is an introductory course which goal is to introduce the basic concepts of the DAX language. A more complete course is the Mastering DAX, which has the same approach going deeper in each topic. If you are more interested in learning practical solutions to common patterns, we have DAX Patterns, where you can find many practical examples without the explanation of how DAX works behind.
