Power BI — DAX Language from Scratch
Is this course right for you?
It goes from first syntax through advanced patterns — calculated columns versus measures, and the evaluation and filter context that quietly govern every DAX result. Filter context is the concept that trips up nearly everyone who learns DAX by trial and error, and a course that tackles it head-on is worth far more than picking it up piecemeal. This is the step from dragging fields around to real analytical power.
It assumes you already use Power BI, so it's the wrong starting point if you're new to it or want general BI skills. Udemy lists a high price but it's nearly always $12–20 on sale with lifetime access — wait for the discount; Power BI Desktop itself is free on Windows. The completion certificate is a learning record, not a qualification (as of 2026).
