Great course ! This course deserves to read more and more as DAX coding reference and to be recommending to all the Power BI learner. Thank you so much for your teaching.

An absolutely amazing course. Well designed Well explained Well delivered Well everything. Can't wait to delve into what's coming next.

When it comes to DAX Marco and Alberto are the real maestros. They are the author of the "DAX Bible" (Definitive Guide to Dax) which is the base of this course. There are other good DAX instructors out there but I have not found anyone that know about DAX inside out as them. The Mastering DAX goes really deep in the fundamentals of DAX and both instructors are very clear on the theory and practical examples that you need to know to master the language. I am very satisfied with this course and it really improved my knowledge and power when it comes to solving business problems by creating BI reports. I highly recommend this course.

This course is unbelievably good. I'm so impressed with Marco & Alberto's ability to take extremely complex topics and explain them in an understandable way.

Fantastic. So happy I chose this course, it was well worth it! What I especially liked was the fact that 90% of the lectures was spent hands-on in PowerBI, writing DAX, looking at the result, seeing what works, what not and why not, improving the code, this way giving you the understanding you need... Also, none of the video of the lectures were edited. They're all single takes, which showed how much teaching experience and confidence Marco and Roberto have. it made everything a much more natural and valuable experience than a lot of other paid online material.

the bestest course! :-) seriously, top notch!

Excellent course congratulations to everyone keep me informed of new features. Very soon I will continue with other courses with you. Greetings Marco Bajana

Very nice and helpful!

Marco and Alberto, I want to thank you both for such a wonderful course. I completed the first one and updating myself with this one also. I could clear the Microsoft certification for Power BI. Thank you so much. You guys are amazing. I truly recommend this course to all Power BI users.

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.
