Understand the difference between a measure and a calculated column, master CALCULATE and filter context (the concept every interview tests), and write time-intelligence measures like TOTALYTD and SAMEPERIODLASTYEAR for YoY growth. Each idea comes with an interactive "predict the DAX output" widget so you compute and verify, not just read. Part of the full free Power BI for Data Analysts course.
