Would I make it to Columbia University?

I am a senior now and I am the captain of the mock trial team and have been in it for 4 years now. I am the leader/founder of a social justice group at my school for 3 years already. I re-founded the speech club at my school and am now the leader of it for 3 years already. I have been volunteering at a homeless shelter located in downtown L.A. (skid row) for 6 years now. I have a gpa of 4.43 and have taken about 5 a.p's. I am the captain of the track team at my school and I am applying under the early decision program. I think my essay is superb, but I am known to be overconfident sometimes. I am trying to enter their school of Political science. I also have a family member whom graduated from georgetown univ. If that would make any difference. Much appreciated for all comments.
