Undergraduate / What can you contribute to our school (but I have nothing to contribute)? [5]

Hello. I'm trying to apply to a certain dorm school, and one of the questions on the application is "What can you contribute to our school?"

I'm not sure how to answer it because I honestly think that I have nothing good to contribute. I'm not a good speaker; I'm not involved with sports, music, or art; I don't have any interesting hobbies; and I'm antisocial... Also, I haven't really volunteered all that much either.

Please help me.
