• Hi! And welcome to my VERY DIFFICULT HARRY POTTER Test. I originally wrote this before Half-Blood Prince was released so there are no spoilers that predate last summer. That said, this is a VERY difficult test ... and does require a THOUROUGH knowledge of the first 5 books. If you say "Accio" to summon the remote or know the exact countdown to Book 7 (or know that if someone says they do then they are lying!) then try this quiz out. Good luck.
