After all very easy labs, this lab it's too difficult and it seams that there are some hidden specifications for the queries very difficult to see and we can't ask what they wat exactly

Tasks 4, 5, and 10 will fail even when identical results are returned. Using subqueries can force all progress checks to fail. It is necessary to sum all "cumulative" case numbers. This is not intuitive because summing a cumulative count over a month returns an incorrect value - if there are 30,000 cases by the end of the month and you take the sum of the number of cases in all days, ~900,000 total cases is incorrect. Please update the instructions or autograder. This has been quite frustrating as a business user.

Tasks 4, 5, and 10 appear to be broken

So bad at detecting the answers - having to copy to new sheet and run again, or structure in a particular way even though not specified (and less efficient!).
