It's a decent introduction. Could benefit from more diverse examples and a slightly better flow between modules.

Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.

Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.

Pretty informative. I liked the practical application examples, though the initial setup took longer than I expected.
