Excellent!

The course is great, I learned a lot! I will definitely watch the course again after some time spent practicing DAX. I would like to thank Marco and Alberto for making a huge effort to realize such good content.

great course

Excellent curriculum and content, worked wonderful with your book as reference. Thank you for adding additional content on Calculation Groups.

This course is Treasure chest full of Gold. However, if you don't practice then this course will be of no use. I am eager to implement DAX in my office projects.

Splendid course that I will revisit along with the relating book.

Thank you for this course, it was extremely helpful!

Thank you, Alberto, Marco, Sergio, and the SQLBI Team! This is the most comprehensive DAX course to date and I am extremely happy to have completed it. I must admit that without the detailed explanation in the "Definite Guide to DAX, 2nd edition" book, which I was reading at the same time I was taking the course, I would not have been able to understand some of the complex topics. However, in certain situations, I did the opposite and re-watched the video after reading the article in the book and got the aha moment.

Fantastic course! Learnt so much about best practices to build a more efficient model.

This is the most valuable course I have invested so far. Compulsory details are explained so that you understand how the DAX engine works under the hood. Exercises are interesting and I wish there are more exercises because that is where you squeeze your brain to think. As other reviewer mentioned, we wish there is more involvement in Power Query

This was a very helpful course in learning DAX. The videos were very informative and I learned a lot.

fantastic course...you are the best even if DAX IS NOT EASY AT ALL!

Excellent! Content was explained in a pedagogical and practical way (on the "demo machine"). Many basic concepts became much clearer along the way. It would have been good to go through the data lineage parts early in the course, since that functionality is not intuitive to e.g. SQL Developers (as mentioned in one of those videos), but affects how one thinks the engine works and thus how one writes code. Also, I think it would have been helpful, at least for me, to visualize the propagation of filters throughout the course - e.g. through the use of Dax Studio (like how a filtered dimension table filters Sales, for instance). Since all this happens automatically, it becomes a bit of an abstraction.

• – Thanks for the feedback, it is very valuable! We know there are students with different backgrounds and the current examples are not specifically targeted to people who have a programmer or SQL knowledge. We are working on additional material that should provide exampled more familiar to those having different former experiences, like the one you indicated. We are going to improve the searches on our website, too - in the meantime, you can take a look at our YouTube channel where we post additional free videos: https://www.youtube.com/user/sqlbitv - They do not cover the specific topic you mentioned, but you might find interesting content, too. Regarding the tools, we are also investing on that side to get better visualizations also for the educational part. You will see the result of these efforts later this year.
