What are my chances for getting into Columbia?

your psat scores are good but your GPA is far to low. Anyone aiming to get into columbia needs to have a 4.0, unless they have a connection at the school. If by your senior year you have a 4.0, which would benearly impossible, loads of extra curricular activies, and get a 1900 or higher on the SAT's you have a chance. Columbia is an extreammmmly selective school so dont be bumbed out if you dont get in. I would stick to trying to get into NYU, which is also very hard to get into, so you better start working your of in school.
