Just awful - Identifying hotspots... tried every way of writing required query. Cannot see anything i was doing wrong. Some guidance would be nice.

Most sql queries can be done using different kind of solutions but not in this test. Also to pass this test you should know sql and platform specific functions or just google it during the test but even if you find the solution it can be a wrong and you need to find something similar

I am pretty sure I found right solution to most of the tasks but the 'Check my progress' test could not pick it up. Very frustrating

Biggest issue: Query 5 answer is not correct, you cannot count the numbers without the summation function. As for other queries, the syntax can be varied to solve a problem. You cannot discard the queries as wrong for using "HAVING" function and then put the same condition in a WHERE clause with an outer subquery. This lab was definitely frustrating as a result
