運用 BigQuery ML 建立機器學習模型：挑戰實驗室 Reviews

Absolutely bad description in the final step. I had to remove the WHERE statement for keeping only the rows with subscriber type = 'Single Trip'. If I selected the start station with the most trips given the above WHERE statement it wouldn't let me pass. At the same time, regardless of whether I included that data when selecting the station, if I also had to omit this WHERE statement when selecting the data for the predictions. In the end I never used the "subscriber_type = 'Single Trip'" filter anywhere. An absolute waste of time trying to figure out what the description means. Giving two starts just because the idea of the challenge lab is not bad and I learned a thing or two. But the description needs to be re-written.

Confusing last task, where query which uses JOIN with bikeshare_stations to find the busiest station yield error, while it gives perfect correct answer.

this lab need a review. Only 1 of the 3 labs i was exposed to actually worked - and the last one worked using a logistic_reg model when it asked for a linear model. Terrible
