Do you think you're the biggest Harry Potter fan ever?
Are you the type that will get 100 per cent on a Potter quiz and think you can outsmart Hermione Granger?
Well this quiz from Wales Online is so hard even JK Rowling would struggle to get full marks.
Give it a go to test if you are a true member of the magical community or just a squib.
The quiz only refers to the books because we are purists - and as any true fan will know there are some big differences between them and the films.
Good luck and remember "don't let the muggles get you down".
