Basically, the answers that you give determines your house.
An example from Pottermore:
You and two friends need to cross a bridge guarded by a river troll who insists on fighting one of you before he will let all of you pass. Do you:
1) Volunteer to fight?
2) Suggest that all three of you should fight
3) Attempt to confuse the troll into letting all three of you pass without fighting?
4) Suggest drawing lots to decide which of you will fight?
If you choose 1), it shows that you are, in a way, brave- which is a Gryffindor characteristic. If you do all the questions with a majority of 'Gryffindor-like' answers, you'll most probably go into that house.

BronzeDragon made this list herself and therefore it is slightly bias, but will still yield close-enough results.
