Coming in with zero BI background, I walked away actually able to model a dataset and build a working dashboard. The sections on relationships between tables and writing basic measures finally made the data model click for me, which is the part I'd always struggled with. The visualization examples were practical and felt like real reporting tasks rather than toy data. I do wish DAX got a bit more coverage beyond the basics, but honestly that's a small gripe. Solid foundation for anyone wanting to step into an analyst role.
