Not Worth the Hype – Except for the Last Chapter This course is largely disappointing and not worth the price for anyone beyond an absolute beginner. The content is extremely basic, with most of the material targeted at users who have never interacted with the tool before. The prompts shown are overly simplistic, and there’s very little depth or practical insight provided. While the chapter titles are attractive, the content often fails to deliver on those promises. That said, the final chapter was a noticeable improvement—it offered slightly more useful insights and felt more aligned with what the course should have been throughout. Because of that, I’m giving the course an average rating. Still, I wouldn’t recommend it unless you’re a complete beginner looking for a very surface-level introduction.
