This course was intensive. Thank you for the example exercises. Thanks to them, I was able to learn quickly

I remember when I first worked with Power BI in 2020 and not being able to make sense of the logic behind DAX made me very frustrated. Nevertheless, I refused to be defeated. I started gathering pieces of information here and there, watch YouTube videos and one day I came across a workshop hosted by Marco Russo. That was the very first time I watched someone talking about the concepts rather than just teaching me ready formulas. I immediately fell in love and thought: I need to learn with these guys! I have since learned a lot following the SQL BI YouTube channel, however, when I started this video course, I knew my life would not be the same. I wasn't wrong. This course is life-changing and the way that Marco and Alberto delivers the knowledge is very structured, detailed and comprehensive. There is no cheating here. They will uncover everything. Yes, sometimes we need to watched more than once to follow their thought process, but this is the amazing feature of a video course. You can watch and rewatch, pause and think along. All I can say is Thank you Marco and Alberto! I would like to extend my gratitude to Sergio, who has patiently and kindly answered all my questions. You guys are true stars!!!!

Best DAX course You can get!

Excellent course to learn the foundations of the DAX language and go beyond the basics. Every video, every exercise is a learning experience, and revisiting it many times really helps to understand the core concepts in a way that will increase your ability to author DAX objects. It is an essential part of any Power BI (and other DAX-related tools) learning path. There aren't enough words to express my gratitude to Marco and Alberto for sharing their experience and knowledge. I'll just say thanks to you both and to all the SQLBI team that helps make these courses, blog posts, and videos possible. I'll promise to keep enjoying DAX!

Great course to perfect Dax skills

Una inversión de alto valor para dominar DAX.

Great, very helpfull

Very good course where everything is explained step by step. I have learned a lot from the exercises which takes practical business problems to be solved also in a step by step approach.

Un gran curso. Muchas gracias por vuestra dedicación!!

This course was quite comprehensive and a definite go to guide when developing Power BI solutions for my clients. Thanks SQLBI team for putting this course together for BI Consultants like me👍

Amazing course! I’d like to review it one more time to make sure I fully understand everything. Right now, I feel like I can solve the problems, but I still need to refer to the documentation and examples to get the solution right. I hope that one day I’ll be able to solve problems as easily as Alberto and Marco!

Please add a new section such calculation group or dax query directly Power Bi Desktop and other new features of this wonderful program. thanks

Excelent !!!

The Course is very helpful. However, the following elements should be included in the course: 01. a video on CALCULATE evaluation steps - there should be a video explaining all the steps of CALCULATE's execution order which will be very helpful. 02. CALCULATION Groups - Calculation groups are generally used in a report with some conditional formatting. For example : for CY and PY values on Sales Amt, Sales Qty the value is always positive and hence the font will be in regular black color however, for YOY, YOY Pct the selected measure should be displayed in Red color for negative values. To achieve such a behaviour requires DAX coding and some tutorials on the same will be helpful. Thanks and Regards,

Easily the best online course I have ever taken, Marco and Alberto do an amazing job.
