It was an engaging course, but I feel that SQL coverage was cursory and the haphazard explanation style of the instructor was not helpful. Still, much useful and practical information.
Learned a lot, and it was fun. I would give 5 stars if it was a bit more challenging.
Could have more exercises and they could be more complex too but in general its a good course to learn SQL and Postgre
