I still don't know

Look at my results. Doesn't this prove I had to go into Library Science for lack of specific focus?
Your in-depth results are:
Hufflepuff - 13
Ravenclaw - 11
Slytherin - 11
Gryffindor - 10

And another test calls me a Ravenclaw:
You are a RAVENCLAW!As a Ravenclaw and as an NFP, you value imagination, ideas and intelligence. You are probably somewhat of an individualist and avoid conforming just for its own sake. You are insightful and perceptive, and since you are empathetic and value harmony, you usually try to avoid conflict. Of course, you may enjoy participating in heated debates, but only as long as they remain on an intellectual level and not a personal level. In general, you are open-minded and curious, and set high standards for yourself.
