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

This was a good introduction. The structure is logical, and it covers the basics effectively. Might be too introductory for advanced learners.

Decent introduction. It covers the basics effectively, but I wish there were more advanced topics or detailed examples for complex parts.
