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.

A solid introduction to the topic. The examples provided were generally good, and the course is well-organized. Just wish some parts were explained a bit more thoroughly.
