    I was already using most of the formulas but this course gave me better practices for their use. good pacing and good building-on of skills during this course.

    Amazing course, step by step level up of DAX formulae with context and problems felt truly interactive. Not just that, it felt like a small problem of a big project that I'm solving in assessments. Thanks to my instructors and data camp for bringing this course to us.
