International Student - Please tell me my chances for these schools!

<p>Ok so I am from the Caribbean so forgive me if some of my exam results seem a bit strange (ie you;re not sure what they mean). I want to ultimately do medicine and I have recently become a permanent resident of the US and so will be living there as of next year. I still, however have to apply as in international student.<br>
The schools I have chosen are Yale University, University of Chicago, Cornell University and Columbia University. Please let me know my chances! </p>

<p>Also, here, required high school ends at grade 11 (starts at grade 7), but sixth form, which is advanced and almost university level, consists of 2 years and so goes to grade 13. They do not refer to the classes as advanced placement directly, but I am wondering if they can be considered as such.</p>

<p>bump :) really need to know. Not that much application fee money to go around.</p>
