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.
Decent course. The structure was logical, but some of the explanations could have been clearer. Still, a solid foundation.
Really enjoyed this. The pace was perfect for me, and the examples really helped solidify the concepts. Got a lot out of it!
Fantastic course. The examples used were spot on and really helped solidify the concepts. My understanding has improved dramatically.
A solid introduction to the topic. The examples provided were generally good, and the course is well-organized. Just wish some parts were explained a bit more thoroughly.
A good introduction. The structure was mostly clear, but I wish there were a few more real-world examples. Still, learned a lot.
Really enjoyed the flow of this. The practical applications discussed were spot on. Great course!
This was a good introduction. The structure is logical, and it covers the basics effectively. Might be too introductory for advanced learners.
Good foundational material. I appreciated the structured approach, although I wish there had been a few more real-world case studies.
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.
