Not satisfied with the results

I like the hands-on, actual work aspect of the lab. But this kind of thing should be the format throughout all the labs. The labs didn't prepare me sufficiently for this challenge lab, because they were just in the format of copy/paste code, and it didn't give me a good understanding. I had to read through most of the labs again as I went through this challenge lab. Additionally, there was no "run step" (or whatever it says) option when I did not get the green check mark on a task. As a result, I failed my first attempt. For the second attempt, I read through and wrote/edited SQL code for each individual task before starting my second attempt, so that I would have more time to troubleshoot if my solution was wrong. I didn't notice the tips and tricks section of the lab until after I successfully completed all the tasks, because it is not mentioned earlier in the lab and it does not have its own header on the right-hand pane. Overall a fairly effective lab, but very poorly arranged and executed.

I believe there's a bug in this lab. The first task asks us to create a dataset with data for the last 90 days, but in task 3 we're supposed to join this to the `bigquery-public-data.covid19_ecdc.covid_19_geographic_distribution_worldwide` dataset, which only has data up to 2020-12-14. Since the two datasets don't cover corresponding date ranges, it's not possible to join them.
