Remember that any filter condition that applies to individual rows will go in a WHERE clause, and come before a GROUP BY. And any filter that applies to the aggregate value(s) will go after it in a HAVING clause.
To enable a more specific and accurate analysis, always show your complete code and provide a link to the course page.
