- In "Practice with STRUCTs and ARRAYs" UNNEST is not explained at all. Only the cross join. What is the difference? How to use UNNEST? - While creating the "fruit_details" table the instructions forget to tell that one needs to check "autodetect schema". - The google_analytics_sample data set was not available when I was doing the lab - 1 hour for such a large and complex lab? It is definitely not enough!

Blocked at step "Creating arrays with ARRAY_AGG()"- not sure how the exercise evaluates that step.
