Pretty good course. The information was relevant, and I could see myself using it. A few areas felt a bit rushed though.

Good introduction to the topic. The structure was logical, and most of the examples were relevant, though I wished for more depth in certain areas.

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.

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.
