关于“从 BigQuery 数据中挖掘洞见：实验室挑战赛”的评价

1. Conditions do not match solutions. Like - to find the number of cases during a month - but we had to use a cumulative value. 2. Task 5 - should have used the HAVING condition on the total number of Italy cases. But the accepted solution is when the condition applies to individual rows. 3. Looker report. Can be done in different way. Custom query was my first choice. But apparently checking script was looking for country selected by country_name. Country_code was not accepted. You either need to provide clear instructions which fields to use in the conditions or have more flexible requirements to the scripts. The solution may come in different ways.

I answered all of the questions correctly but the progress tracker was failing

The AI is messed up for Task 5. I have done this lab twice. I updated the limit for the second time. I know the date the query is finding is right, but I cannot get a green check mark. Task 7 is messed up as well. I have met the requirements, but I cannot get a green check mark. Task 8, I calculated recovery rate and got the list of 20, but cannot get a green check mark. Task 10, my Looker report is filtered for United States of America and the data range specified. The report looks like the one given as an example, but I cannot get a green check mark.

I found some of the queries challenging as I was able to achive the results but not using the accepted code syntax etc
