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.

I recently completed a DAX course at DAX, and I must say it was an outstanding experience. The course content was comprehensive and well-structured, providing a deep dive into the intricacies of DAX. The instructors were knowledgeable and engaging, making complex concepts easy to understand. The sheer volume of information covered in the course was impressive, and I found myself constantly learning new techniques and best practices. It's clear that this is a course designed to be revisited multiple times, as each review reveals new insights and reinforces previous learnings. Now, the real challenge begins: putting this newfound knowledge into practice. With time, dedication, and consistent effort, I am confident that I can master DAX and achieve my goal of becoming a DAX Master.

Great course!!!

A well explained, guided and challenging course to test your DAX skills. I feel like I have such a better understanding of the engine that will now allow me to write optimised DAX solutions and where previously I only knew how to do it in sets ways without 100% being able on how to explain it. This is a very valuable course in order to get yourself to the next level.
