Agree with above. Also, with so many possible quotes, it would be nice if all the answers were different. Otherwise, design it as a yellow box quiz so all the answers that are the same don't automatically fill in when one is filled in.
got all but filch and quirrell. also, you could just accept surnanes of forenameslike just harry, ron and hermione. Also it's spelt quirinus quirrell. You should get the write answers for a quiz
I got that wrong because of the spelling but good quiz overall :)
