Crunching Data for Absolute Beginners: Learn to Code with Microsoft M-Language for Excel

I wrote a tutorial series targeted at absolute beginners to programming.

I am a beginner myself, just a step ahead of my target audience (takining a peer to peer learning approach here).

Can you give me feedback on that series? I am curious to hear your thoughts and how I can do better. Thanks!

(PS: I am targeting both Excel & Power BI users)
