Some referenced fields in the ga_sessions_20170801 table have different letter cases, than as written in lab instructions. Also in the task before the last one, you can ommit the UNNEST commands, and BigQuery still displays correct result. Only the lab will not accept it, even when it is correct.

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.
