The instruction was a bit hard to follow at times. I had to rewatch several segments, and the examples weren't always clear.

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.

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.

Learned a good amount here. The examples were relevant, though I wished there were a few more practical application tasks. Still, a worthwhile experience.

Pretty good. The practical aspects were well-covered. Might be a bit fast for complete beginners in some sections, but manageable.

This was a good introduction. The structure is logical, and it covers the basics effectively. Might be too introductory for advanced learners.
