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.

Excellent course; I only wish there were a much longer and more robust lab on optimizing query performance, after all the tips we learned in the corresponding lessons.

I learned lots about the structs and arrays and how it could be used to improve performance by creating parent child relationships instead of doing expensive joins

Lots of in-depth material covered in this course, including nesting of data structures. Also provides high-level introductions to Google Data Studio and Cloud DataLab.

Excellent course on BigQuery, Dataprep, DataStudio and Dataset Secure Access topics. Hoped to have more on Datalab and Bigquery, and also more difficult labs, but it's ok.
Overall this was a great course with great material.
Thanks!

A lab on notebook would have been nice.
