Well, as far as quizzes go, i guess it works.
But you're making it too difficult for people who don't listen to classical music frequently to answer correctly. The Answers should come as buttons, with multiple choices, except for an open-ended answer that might be wrong if i don't write the artist's name correctly (i wrote "wagner" without a capital W and didn't get the score because of that, see where i'm getting to?), it makes taking the quiz extremely time consuming and boring.
Next, try adding a bit more eye candy to the flash, if the quiz is about classical music, i don't understand why there's a background more suited to techno of the 80's and a black font that honestly clashes horrible with the background. Its legible, yes, but not pleasant to look at.
All in all, it just needs polishing. Also, try adding correct answers written by yourself with a short explanation of why, when and where, like when did X artist compose it with a bit of trivia, instead of "it was him did you get it right?".
Offer us something that we haven't seen before. :)
