What are my chances of getting into Ivy league college?

Your chances are alright. Do well on the standardized tests. Ivies are hard to get into, though. Apply and see what happens. There are other great schools in the U.S. that aren't Ivies that you should also apply to. These include Stanford, Georgetown, U Chicago, Tufts, Boston College, Middlebury, and Bowdoin. You have a good shot at these schools (well, Stanford is as selective as Ivies) and they are great schools. Good luck!
