This is not a good lab. It seems in some cases that queries that return correct results do not pass the Progress Check. Also, some queries that pass the Progress Check seem to be me to just be wrong. This is especially obvious on Task 4. But on others, where we add a filter for country_name and we do not include aggregation_level = 0, it seems that we would be double counting (ie summing both the country level and the state level data, a classic DW double-counting issue), but these considerations are not factored in to the solutions that pass the Progress Check. On Task 10, we are asked to use Looker Studio. All previous labs used Looker, which is not the same thing. Before trying this Challenge Lab, go into Skills Boost and find the Looker Studio Quick Start lab, and run through that first. When running this lab, be prepared to burn a day, repeat it several times, and contact Qwiklabs support when you run into issues. I got it on the 3rd attempt. I have 25+ years experience writing complex SQL queries and 7+ years using BigQuery. I'm not a rookie.

I write queries that get the correct answer but do not get credit. I change the syntax, get the same answer and then I get credit.
