Thank you Marco and Alberto, this course is obviously the best around, for the content, of course, but I also very much enjoy the 2-person animation and the large number of exercises (from an instructional design point of view, a very well-built course).

i get additional insights every time i watch this course

Excellent work

Excellent! Any other adjective would not describe the quality of this course. I would suggest nevertheless that you introduce "exam"-like exercises (that are not joined by solutions) and are graded. This indeed will guarantee an in-depth knowledge of the material covered.

• – Thanks for the suggestion! While we prioritize the production of content and tools for learning, certification is a process that is not currently in our goals. We do have a self-assessment exam to review pre-requisites for Optimizing DAX (did you try it?) and we would like to extend that approach further, rather than provide a certification assessment. We will consider your and others' feedback in our future plans!

Fantastic course by Marco and Alberto covering all aspects of DAX and complex Power BI models. The best part of the course is that they not only teach you what is best practice but also tell you what not to do and why you shouldnt it as well. Highly recommend if you want to master DAX.

Definetely this's the example of how on-line video course shoud be made. It's up-to-date, includes professianally made support materials (demo files, slides, exercise book), covers deep theoretical nuances of dax logic (which is the foudation of your ability to write and uderstand how code works). At the same time, there's a huge amount of sophisticated exercises (especially advanced section) that helps you to get practical skills. Also, thanks a lot for your blog and tools like dax formatter. Your blog posts should become the next step in learning all the technics and nuances of dax language and proper data modeling.

I love this video course!. Excellent and simple explanations of the most used DAX functions and are available at any time you need them. Thanks Marco and Alberto, keep going doing with this kind of courses.

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.

Hi Marco , Alberto. The course is absolutely amazing. After going through this course, I bought your "Data Modelling" course. Great content, excellent delivery. Just one suggestion, Is it possible to provide a data or data source from a different industry may be IT, along with list of exercises to solve. This can act as a project and also help us to test our understanding. Thanks, Swapnil

• – The reason why we use always the same sample data (Contoso) is because this allows the reader to focus on the exercise/module topics rather than the details of the implementation. This is especially true for the DAX course. For Data Modeling we already introduced different data models in order to present and to solve specific modeling problems. However, in those cases the amount of data included is very limited. The reason is that sample data must satisfy a number of requirements and not create any issue related to privacy, NDA, and advertising. The Contoso sample database is a huge investment that Microsoft made 10-15 years ago. In such a database, all the names have been cleared for publishing. Similar investments are certainly not possible for a single video course. Therefore, while we agree that adding specific industry-related models would be very useful, it is unlikely to happen - at least considering a data model populated with reasonable data, like Contoso and Adventure Works.

I love this course!. Excellent explanation of DAX functions and I can review every time I need to remember some function. Thanks Marco and Alberto for dedicating your time doing this course paying attention to every detail.

Great Course. Very interesting and with lots of useful examples

Outstanding! an incredibly full and thorough course. Thanks Marco and Alberto for creating such a valuable product for those who seek to expand knowledge in DAX.

The best platform to learn and implement DAX. Thanks for all the awesome videos.

This is very good class and is very involved. I will have to re-watch some of the parts of the class and re-do the exercises. The main problem with DAX for anyone who is coming from T-SQL experience is that the principles to query the data are very different. You need to reconfigure your brain.

Great course! Highly recommended and sharing my experience on LinkedIn. I found the course challenging and insightful and while I didn't get the format right on many exercises the first try, I did understand the concepts; so I felt the delivery of training was impeccable. I passed exam 70-779 Excel and this course will help me secure a passing score in 70-778 PowerBI. I fully intend to continue my studies here with the next level courses. Thanks again! Tom
