Appreciation Post
I cannot express enough how grateful I am for Zach for offering free high quality content. As an econ student with a recent switch of interest in data, all the lessons excellently delivered by Zach, though "a little" hard-core for me, gives me a solid foundation in DE. It taught me a lot, especially in terms of hands-on experience, how DE is a critical in making business decisions, how mastering the underlying fundamentals makes chasing trend-setting tools seem obsolete.
