What are my chances of getting into Columbia?

Hi I’m a senior in high school with a 4.2 gpa, a 1220/1600 (680 CR/ 520 M) SAT score, and I am taking the ACT this saturday. I am my Key Club chapter’s president, I am in BETA Club, FBLA, NHS, and Art club. My school is a free- lunch school. What are my odds?
