    Dax formulas is not that easy to understand, but this course introduced this issue in a very simple and clear way. I'm excited to see the coming courses of this track.

    I've come from a R / Python / SQL background, and this course was very helpful. I still find DAX and Power BI conceptually difficult, because I find it hard to visualise what's happening, nonetheless, this course got me going.
