Solid content here. While a couple of the modules could have been more detailed, the overall value and applicability are high. Good job!

It's a decent introduction. Could benefit from more diverse examples and a slightly better flow between modules.

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.

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.
