Harry Potter Quiz

I count myself Harry Potter's number one (times one billion) fan. In the aftermath of a particularly fierce rush of loyalty to the books, I decided to create this item. May I warn you now that unless you have a very thorough understanding of the books you'll find a lot of these very hard. The first person to send ALL the CORRECT answers by review will recieve 300 GPs by return mail. Not much, I know, but it's the thought that counts, right? 
Good luck!
