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 good course if you have some prior knowledge. For absolute beginners, some concepts might be a bit challenging. The structure is logical, 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.
Hmm, I'm not sure this is ideal for beginners. Some concepts were glossed over, and the examples weren't always clear.
Good introduction. I appreciated the clear steps, although some of the later modules could have used more examples.
Thoroughly enjoyed this course. The way the information was presented was excellent, and the practical applications were highlighted effectively. Great job!
Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.
This was a good introduction. The structure is logical, and it covers the basics effectively. Might be too introductory for advanced learners.
Brilliant course! The structure was intuitive and the actionable insights are invaluable. Highly recommend.
Not worth it. The course felt very poorly put together, and the information wasn't useful in any practical sense. Avoid.
