Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.

This was a decent introduction. It covered the basics well, but I was hoping for a bit more depth in certain areas. Still valuable for beginners.

A good introduction. The structure was mostly clear, but I wish there were a few more real-world examples. Still, learned a lot.

It's a decent introduction. Could benefit from more diverse examples and a slightly better flow between modules.

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.
