Chances for Columbia, Barnard, and NYU

<p>Hello and thank you for taking the time to read this!
I am currently a sophomore at an extremely competitive IB public high school and I have a dilemma. I plan on graduating a year early (at the end of my junior year) in order to move up to New York to pursue college and modeling. I already have a contract with a top agency in New York and am hoping to continue modeling and go to school.
Last summer I got the opportunity to live and work in Tokyo for two months and this summer I plan to go to Paris to work. I have had a wide array of experiences with people from other cultures and I plan to write about this in my applications essay. I may even send my application from Paris!
However, my question remains: Am I good enough to graduate as a junior and attend a top-tier school? Or should I stay in high school another year?</p>

<p>I know that most of this information is theoretical and is likely to change, I would really love to hear some estimates on my chances. Thanks to anyone that can help!</p>
