To find which house you should be in:

Click Harry Potter Chat
Click Hogwarts School of Witchcraft and Wizardry
Click Slytherin
Click Which House are you in?
Click Are you evil enough to be in Slytherin?

"You can take the quiz here (underlined)."

Click here (underlined)

You take the quiz and then you are sorted into the house of your choice.

This quiz should not be in Slytherin because it refers to all houses. But anyway,
give it a try.

Good luck.
