That is UNCLEAR that columns during model creating MUST be named exactly "dayofweek" or "hourofday". Even when I tried same words but with other register (DayOfWeek) I cant pass last check

Lab Task 3b wasn't working for me. It isn't clear what the CONCAT should be. I wrote: CONCAT(CAST(EXTRACT(DAYOFWEEK FROM pickup_datetime) AS STRING), CAST(EXTRACT(HOUR FROM pickup_datetime) AS STRING)) AS day_hour_cross, but that wasn't right, and logically it should be right. So unless there's a different format you want, it isn't clear. Waste of 5 credits.
