This was a good introduction. The structure is logical, and it covers the basics effectively. Might be too introductory for advanced learners.
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.
Good foundational material. I liked the mix of theory and practice, though a couple of the examples could have been clearer. Overall a positive experience.
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.
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.
A good introduction. The structure was mostly clear, but I wish there were a few more real-world examples. Still, learned a lot.
A truly excellent learning experience. The flow was logical and the examples were super helpful.
