How big of a Harry Potter người hâm mộ are you? 

What a poor quiz... some of the questions. You'd only ever have copies of the books in different languages if you were fluent in many. Some people can't afford to travel to those places or live too far away. That wouldn't make them less fans. And other stuff..... generally I'm glad I've never been obsessive enough over ANYTHING to dress up as a character or go to any midnight screening. And that makes me a new fan? I've had the books since I was 12!

You’re a half-blood and there’s nothing wrong with that! Some of the best and bravest wizards are half-bloods. You’re dedicated to the cause but have yet to really dive in. There’s still plenty of time to further your studies. If there were an O.W.L. for Harry Potter knowledge, you’d get an E.

@Flickerflame: Personally, I don't think going to a midnight screening or dressing up for a party that happens once makes you that obsessive. Also, why bring up issues like poverty or knowledge etc? It's a simple test to fill your free time! Nobody said it can read your mind! I can only reassure you that no matter what their financial status is some people actually choose to spend money in fandom over clothes or things they really need. This is unhealthy in my humble opinion, but one thing that is certain is that they 'll get a higher score than me and you in this test! :P

What I meant is that it's easier for those who live in England to go to these places, but that doesn't make them better fans than anyone who lives elsewhere. Same with owning many copies or different languages - why would you do that if UK English was your first or only language?

My second point was issues with how it gives the results. Saying that a less "obsessive" fan (doesn't go to conventions, to these places, midnight screenings etc) has to be new to the fandom. And in higher scores, saying that a "pureblood" result is better than "halfblood" or "Muggle born" when one of the main messages within the series is the opposite.

I know what you meant and I probably agree up to some extent, but it's just a fun quiz. Keep in mind that no internet test can really tell who's the greatest fan and who is not, no matter how accurate it seems.
As for the last thing you said, the person who created the test probably meant that a "muggleborn" fan is less familiar with the magical world aka a newbie fan or something like that. While the pureblood is the die hard fan because they are really into Harry Potter magical world like the purebloodss are born in this world. But yeah, it wasn't that wise of a choice to use these terms.
