The knowledge and enthusiasm of Marco and Alberto around DAX is really impressive :) Due to the complexity and difference of DAX compared to other ways of coding and syntaxes, I found some of the lectures quite hard to follow. Maybe it could be good in some looooong chapters to have exercises spread out inside a chapter instead of only in the end. I don't feel as a Master of DAX, but at least I know a lot more know about what is possible (and not possible) to do :)

The course is very complete and allowed me, since the begging, to use DAX in my power BI reports and bring them to the next level. Although, I think there are same basic concepts especially for the data model part which are omitted here and I would like to deep dive in.

• – Hi Jacopo, We dedicated an entire video course to data modeling. Please look for the "Data Modeling for Power BI" video course and start with the free trial to see if that is what you were looking for! Thanks, Claire

Very helpful, Great demonstrations!

Well organized, very informative and the examples/excises are helpful while progressing the course. Thank you!

Very broad explanation for some formulas DAX. However, there are some features and solutions to them that are outdated. In some case it is dificult to understand the content due to not understanding well the meaning of some words such as filter context, iterators etc. I think there should be some vocabularly or introduction to this specific words.

Dense but good!

Great course, have to do it a few more times to master everything.

Muy buen contenido.

It is okay.

Clear explanation of the different DAX items. It has helped me create dax formulas. The difficulty for me now is to make DAX formulas that have nothing to do with Sales, but with analysis of delivered products of technical modifications per engineering department. I just have to figure it out, because there is no one in the department who can help me with DAX, but during the course I was already able to apply it in practice.

Great course with a great attention to detail and a easy to follow step-wise learning module. The explanations of the presenters are very clear. The excercises however often included subjects and code of future lectures, that made some excercises nearly impossible to solve with the current knowledge. This demotivates a bit, as solving excercises correctly makes you want to continue, whereas continuous struggling with the excerices is a tad annoying.

• – Hi Wout, just a clarification: the Advanced exercise we have in the initial chapters have been included for people who start the course with existing knowledge of DAX. For this reason, they have additional prerequisites. Only the Basic exercise should be completed with the knowledge provided in each section, the Advanced one should be considered optional. We included them because we had the request for more challenging exercises in the initial sections. However, we have to better explain this in the video course, we are working on that and it should be fixed soon. Thanks for your feedback!

Finally I am done. Learned a lot of DAX concepts. Thanks

This is the most comprehensive course you will find on DAX anywhere. I found it helps to read along in the book ("The Definitive Guide to DAX") and then watch the videos as I go. The book mirrors the course content and order almost exactly. The one thing I hope they improve on are the exercises. For most modules there are one to three exercises but for some there are none. I would definitely understand the content and retain the knowledge better if there were more examples to work out for each module. While some people who take this course can apply the knowledge directly to there work others, like myself, don't work with DAX in our days jobs but eventually want to so the more exercises we can try the better. It could even benefit from quiz's along the way and a test at the end.

I think it's been a good course, and that Marco and Alberto do a great job explaining DAX. I'm still not fluent, but feel slightly better equipped to go forward.

The courses are indeed the masterpiece and excellent but, please fix the site. Its very slow and works poorly if the internet speed is little low. Fix the site please, this is the only demerit I find and that's why rating this 4 star but, again the courses are excellent and so as the instructors.

• – Please, can you provide more details about your issues? Most of the time that a user experiences a problem with the videos, it is because of a firewall or an antivirus that slows down the connection. You can lower the resolution of the video to reduce bandwidth consumption if your internet connection is slow. If you experienced other issues, please clarify so we can investigate. Thanks for your feedback!
