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.

Hmm, I expected more practical application. The explanations were a bit abstract and I'm not sure how I'll use this yet.

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