I learned a lot from this course: it gave a great overview of what’s possible both right from the UI, and what more awaits if you lift the hood and pimp the engine. It’s incredible to see just how much PowerBI and PowerQuery radically simplify what I would otherwise have to do with many, many lines of complicated VBA code. And Reza is a masterful user of this tool.
Note that Reza covers a lot of ground in this course, and it is pretty fast paced. While you can take a laptop and follow along as Reza takes PowerBI/Powerquery through its paces, for the one-day course my recommendation would be to keep that laptop closed, and simply sit back and watch Reza in action, so you can fully concentrate on just how simple this tool is to use in the right hands as well as think about how you might use the tool to your own ends and ask questions along those lines. You can always purchase the video course (if it’s not already included in your course) and step through the material again at your own pace.
