As Kudose points out, we need to see the schema (or structure) of the applicable table(s) in your database to help.
In general, if you had a date column called report_date, a points column called points, and a column containing the user's name, user_name, you would do:
SELECT user_name, points
FROM reports
WHERE MONTH(report_date) = MONTH( CURDATE() )
ORDER BY points DESC
I would recommend that you never using a "SELECT *" query and instead only SELECT the columns that you actually need data from.
