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.
