Harry Potter general knowledge

I don't mean to be critical, but yes I do. There are a lot of things wrong with this quiz: 1) the spelling. 2) inconsistency. 3) answer acceptance. I typed Prongs five times, all spelled correctly, and it didn't accept it. Same goes for at least one of the book titles. As for spelling (or thereabouts), hoo boy. Gryffindor, not Gryfindor. Hogwarts, not Hoghwarts. Sybill. Prisoner. Durmstrang. Also, it's unforgivable curses, not unforgetable spells, though they are certainly unforgettable as well.

So, inconsistency: Your answers for the books only sometimes required the word "the," other times not, and they should all be the same in that regard. I didn't know whether you wanted "Harry Potter and the Chamber of Secrets" or "Chamber of Secrets" or "The Chamber of Secrets," and it wasn't the same every time so I just gave up. Then the Hogwarts professors: You included such characters as Lupin and Hooch but not Slughorn, Quirrell, Umbridge, etc. I mean, I love HP quizzes, so thanks, but....
