This course is the most comprehensive course I could find regarding DAX. Here a couple of opinions. There only needs to be 1 instructor per section and the instructor does not need to be in the video. It would be nice to see the slides and the computer screen without the instructor obstructing the view. You would also benefit from not having to rely on the other instructor to fit the screen or go back to a function, etc. It feels like you are stepping over each other a lot. I feel like you are trying to make the questions seem natural but it doesn't work. Outside of that. Excellent course.

Very thorough in depth course. It can be confusing with all the scenarios and solutions but this is what it's like using DAX for real.

I have just finished my course only to find out that I have only done 97% How do I locate the 3% not covered?

• – You should check in your course what are the lessons that are not marked as "completed" - you can change them manually (maybe the browser did not send the notification for some video you already watched).

All Good!

Generally, I think that the course is good. It could be improved to be excellent by adding more detail in the exercises and their solutions. For example, although most tables and pivot tables are obvious to set up, some are not. So, clear descriptions of which fields to use for the rows, columns, and values would improve the courses. In addition, explanations, perhaps in the form of comments in the DAX code, describing the rationale and logic for the solutions would be good (e.g. why something had to be done a specific way).

• – Thanks for the feedback. In a few weeks we'll release a new version of this video course (and you will get automatic access, of course), which will include a brand new set of exercises. We considered all the feedbacks we received and while we are not able to satisfy all the requests, I hope that you will enjoy the new format.

The course is very dense, as I expect but the many growing concepts and the hard exercises are in a level that not correspond to the video classes. Video classes are easy and in a lower level presented. Perhaps , as a suggestion you could send us videos about the exercises resolution. The forum in that case is not enough. I realized that was a "jump" between the classes and exercises. Intermediate exercises between them could be another strategy to consolidate the concepts before going direct to the complex exercises.

• – Eduardo, thanks for the feedback. Any example of intermediate exercises would be useful - we know that we have several exercises that we consider basic or intermediate, and we can imagine what you consider advanced, but a more detailed explanation would be very useful for our evaluation. Thanks!
