QuestBridge

What are my chances of becoming a QuestBridge scholar?
My SAT is a 1210 but I am retaking it
My GPA is a weighted 3.875 and an unweighted 3.375
My extra curriculars are outstanding including working on a political campaign and having a job at a professional theatre.
I have attended 6 different high schools
I am considered a homeless student
My counselor said my essay is stellar.

If I have ALMOST the middle 50% grades and scores for QuestBridge scholars but an extremely unique story (I am legally homeless and more) what are my chances of getting Chosen as a finalist? My essays and extracurriculars are amazing. How holistic is the process of choosing a finalist?
