Good material overall. Some parts moved a bit fast for me, but the core concepts were explained well. Useful for building a foundation.

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

A solid introduction to the topic. The examples provided were helpful, but I wish there were more opportunities for hands-on practice.
