Lab is good and interesting. Only issue is Lab expect exactly same query. Ideally it should verify the result and approach. Some places description is not clear.

Queries in Big Query platform doesn't give accurate results and there's no way to find the correct solution.

Time is short and several queries were not acknowledged, even though what was requested was returned.

I spent more than an hour on Item 2 and couldn’t get any further. SELECT count( distinct subregion1_name) AS count_of_states FROM `bigquery-public-data.covid19_open_data.covid19_open_data` WHERE country_name = 'United States of America' AND subregion1_name IS NOT NULL AND cumulative_deceased IS NOT NULL AND cumulative_deceased > 100 AND date = '2020-06-25'

This is a tough course because the fields are not defined well. There are also things like counting USA states, but you are actually referring to territories, possessions, and Federal Districts as well. I would love to help proof this course should you decide to give it an overhaul. I think this is important, as getting a 100% in the course is critical to gaining a badge. Thank you.
