Task 4 step 5's query is missing a "," after `location.country`. Funnily enough, the query runs but it gives US as values under "cost" column. Task 4 step 10 question's answer has no actual match (Found 62 record entries for Cloud Storage above 1 dollar on the given query). The accepted answer is "Cloud Storage has 17 charges costing more than 62 dollars" which makes no sense. Querying "cost > 62" yields nothing, checking SUM(cost) on "cost > 0" yields 753 entries for Cloud Storage totalling $240. Meaning if there are 17 entries costing more than 62 dollars, it has to sum to at least $1054.

I found two mistakes: In one multiple choice question the "correct answer" has a mistake, it should read: Cloud Storage has 62 charges costing more than 1 dollar. In three example queries to copy+paste into BigQuery there is a syntax error in that a comma is missing separating the values of the column names to be displayed. The result is that after running the query one of the columns has as title the name of Column A, but the values of Column B..
