even though you have the correct results and a correct sql, the check my progress button can not verify the objective. For example you should not give the table an alias or you will never succeed in checking the progress. Or if you use an subselect instead of an with statement in task 2. Or... I don't know, I lost my patience at Task 3. with deaths_by_states as ( select subregion1_name as state, sum(cumulative_confirmed) as confirmed_cases FROM `bigquery-public-data.covid19_open_data.covid19_open_data` where country_code = "US" and date = '2020-06-25' and subregion1_name is not null group by subregion1_name ) select state, confirmed_cases as total_confirmed_cases from deaths_by_states where confirmed_cases > 2000 order by confirmed_cases desc
