How do I know what house I am supposed to be in?

:)
Hey.

That's easy; you must get Sorted. Just head on over to the Sorting Hat Questions, copy the questions, paste them in Sorting Hat Answers,and answer them. Then after a few days, Professor Rouge will tell you what house you're in.

Let me know if you need more help :)

oh and don;t fiorget sometimes rogue is a little slow with sorting, after all he's not the flash and he can't do everything as superspeed so just remembner that if he doesn';t sort you in like a couple of weeks after you take the test, you should PM or email him. that's what I had to do.
