Useful practical course, especially about performance optimization. Window functions have many options, it would be nice to add window size description with practical examples or links to them.

I really appreciated all of the labs that went along with this course. They were detailed and thorough and led us through some advanced concepts in a digestible, understandable fashion.

I had trouble with multiple labs and the support team couldn't resolve the issue for me in time to finish before the due date. Still glad to have completed it and that the labs count even if they are completed later.

The course content was good but there was a problem with audio quality. The audio was too low.

So I cut 2 stars from the rating.

The courses on Google Data Studio and Cloud Data Lab are not extensive enough even though they are well taught.

labs were very superficial in places that would require strong practice. they should have gone more in depth

Os "Labs" são muito fracos, gerando poucas oportunidades de prática para sedimentar o conteúdo.

the course needs more labs more extense and deep, in order to have a real knoledge. This course only introduce tools and concpets but you must touch more in order to really understand.
