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.

Helpful material. The structure was logical for the most part. Might not be for absolute beginners though.

Hmm, I'm not sure this is for beginners. Some parts skipped over foundational concepts too quickly for my liking.
