Solid content here. While a couple of the modules could have been more detailed, the overall value and applicability are high. Good job!
Exceeded my expectations! The structure was logical, and the real-world scenarios really helped cement the learning. Great value.
Honestly, pretty disappointing. The concepts weren't explained well at all, and the examples were confusing. Wouldn't do this again.
Good introduction to the topic. The structure was logical, and most of the examples were relevant, though I wished for more depth in certain areas.
