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.

The professor explains really well and I thought the content was very descriptive and informative! I was not a fan of the exercises, thought they could be a little better explained or approach more complex problems. The access to Big Query labs though is really great feature! Overall, It's a good course for those who are going to use Big Query!

Nice robust intro into advanced SQL on GBQ, Big Query architecture & Cloud Data Lab. Lots to learn or review here even for seasoned basic SQL users. Also lots of value in Google Cloud Platform's suite of integrated data analytics products.

Good overview of many more-advanced features of BigQuery as well as intros to DataStudio and DataLab. However the practice labs were a bit too easy; more in-depth practice would have been useful.

Very interesting topics, engaging instructor, I would need some hands-on exercises to better understand the material. Maybe a capstone project at the end of the specialization would be ideal.

Some of the labs were short, but some great stuff on nested data, window functions. Fixing bad queries section was good, I had already found 'avoid self joins' through experience.

Arrays and Structs could have been explained better and more practice on these topics could have been helpful. Otherwise the content is very good and informative.
Amazing course . Some lectures should have had more exercises in lab for us to practise.Overall a very good course which provides a hands on experience in GCP

Everything was very good except for the sound problem. Your sound volume was so poor. You need to talk more loudly.

Very Good Content, Only concern is Audio Volume is low during presentations even when listening through headphones

Good course, more detailed/complex but practical scenarios in data warehousing space would be appreciated.

The explanations were crystal clear. Could provide more practises to solidify understanding.

The course was fun with learning. One suggestion to improve the video player somewhat.

Really interesting the topics related to Big Query Performance and Nested Tables.

I am excited with Bigquery Advanced concepts and giving me a great learning.

The course is great but there are some technical issues with the labs.
By mika R•
more tricks during the lab would be nice
By Giorgio M•

Content of the training is good. Pace of the training is good but the audio decreases/fades all of a sudden. Its hard to hear the instructor unless you have headset on. I recommend to keep the training in a same regular volume from start to end so students don't loose focus due to faded volume.
The course fell short of my expectations because, in spite of its ambitious content, not enough labs were provided. Two important topics ended up without being practiced: Notebooks (the equivalent of Jupyter's, whose name I don't remember just now) and permits and column security.

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.
