Very poorly worded and explained. You ought to employ people with some teaching abilities.

Some of the task instructions were unclear without fully understanding the schema, as there are no descriptions of the fields. The same fields are used in different ways in later tasks, causing further confusion. In some cases I found it difficult to write the query without looking at the suggested answer. Also, I wasn't sure whether I was supposed to be writing queries myself or just copying and pasting the queries provided. And sometimes no correct answer was shown to confirm whether my query was correct.
