What are my chances

<p>I have a 4.3 overall gpa, a 3.97 unweighted and have not finished junior year. I expect to have a 4.37 overall after the year is over with a 4.62 10-11 gpa. I will end up taking 10+ AP courses and will be valedictorian. My college essay is like no other in that i am suffering from a rare and incurable heart disease. I have had about 7 club positions and am thinking about making a 501c3 non-profit. My SAT is a 2040 with a superscore 2060 and i plan to take it again in june. I want to go to Stanford, northwestern, or Columbia as reaches or to UCSD, UCLA, University of Virginia. What are my chances and any other suggestions for schools if i want to major in econ and polisci?</p>
