Solid content and presented clearly. I appreciated the real-world applications shown. Could have used a few more practice opportunities.

Tbh, I expected more practical application. It felt a bit too theoretical for my needs, though the core concepts were explained okay.

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