There are a few bugs that need worked out. For example, in practice questions if I make a mistake and the query can not be run, then the app locks up with an error message. I think maybe the message close button is just off screen. The only way to progress is to close the app and you lose the work you put in on the query. Next, not sure the judge should be so picky on the column names of query’s. I spent a lot of time on one query and my query logic was good but I did not capitalize a column header. Took myself a lot of time and even stumped chat gpt for a good half hour. The focus should be on learning.
