Generally great, however I found an issue with one question. The instructions ask to execute this query: SELECT service.description, COUNT(*) AS billing_records FROM `billing_dataset.sampleinfotable` WHERE cost > 1 GROUP BY service.description ORDER BY billing_records DESC on test data set The question is: Which product had the most billing records of over $1? - Cloud Storage has 17 charges costing more than 62 dollar. - Kubernetes Engine has 7 charges costing more than 1 dollar. - Cloud SQL has 15 charges costing more than 1 dollar The resulting of the sql query: description billing_records Cloud Storage 62 BigQuery 29 Compute Engine 2 The answers are wrongly formulated because there are 62, 29 and 2 charges that cost over $1. Instead the answers wrongly indicate that there are 17, 7 and 15 charges resulting in cost of more than $62, $1 and $1 respectively, which while generally true, technically none of the answers are correct.
