What house...
Honestly, having personally done many different official and unofficial tests, I'm first and foremost a Ravenclaw, with ash or aspen wood and a dragon heartstring core, depending on how long and precise the quiz is. But Sifr, my character, showed more Hufflepuff characteristics on this site's quiz with a unicorn core, while I come out as Hufflepuff and Gryffindor equally as a secondary house on other sites. My character is different from me, but I figured I might unknowingly influence my character's choices.
