Found it a bit dry, tbh. The examples weren't always the most relevant, making it hard to stay engaged through some of the modules.

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

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

The course covers the basics, but I'm not sure how applicable it is for real-world scenarios. Needed more practical depth.

It's a solid course. The structure is logical and most of the examples were helpful. Could use a few more real-world scenarios though.
