I liked the discussion part of it as it would give you a deeper understanding of the SQL query required for the question. Yes, you can also use it to cheat (wink) when you don’t know the answer to the question.

I found PostgreSQL Exercises very useful and I am on this website right now to get some practice SQL sessions. Check out this cool website, practice SQL with these free exercises and polish your skills.
