Task 2 is bugged. This was my query but it didn't pass, it expects to evaluate 2 models while we have only 1 model. SELECT * FROM ML.EVALUATE( MODEL `qwiklabs-gcp-03-4b3a498f05c5.ecommerce.customer_classification_model`, ( SELECT * EXCEPT(fullVisitorId) FROM ( SELECT fullVisitorId, IFNULL(totals.bounces, 0) AS bounces, IFNULL(totals.timeOnSite, 0) AS time_on_site FROM `data-to-insights.ecommerce.web_analytics` WHERE totals.newVisits = 1 AND date BETWEEN '20170501' AND '20170630' ) JOIN ( SELECT fullVisitorId, IF(COUNTIF(totals.transactions > 0 AND totals.newVisits IS NULL) > 0, 1, 0) AS will_buy_on_return_visit FROM `data-to-insights.ecommerce.web_analytics` GROUP BY fullVisitorId ) USING (fullVisitorId) ) );
