I like that there are summary after each section to recap what was learnt. However, for the last few queries, it seems like UNNEST was unnecessary and the same result will still be returned without using UNNEST.

The queries with cross joins or commas and unnest can be run without the unnest part. They will work and yield the same result (I think its unnesting under the hood) but they won't count as the right answer in the progress check. Maybe you'd like to add those too
