This was a good introduction. The structure is logical, and it covers the basics effectively. Might be too introductory for advanced learners.

Decent introduction. The structure was logical, but I wish there had been more hands-on practice beyond the basic examples.

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

It's a good course if you have some prior knowledge. For absolute beginners, some concepts might be a bit challenging. The structure is logical, though.

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.
