You talk about “applying to a few Ivies.” Stats and EC’s aside (EC’s are great, GPA competitive, stats low - I don’t think we can tell you anything you don’t already know) - you should be thinking about the “Ivies” and other schools that are the best FIT for you, not the most prestigious. All 8 Ivy leagues offer very different experiences and there’s no guarantee they’re all somewhere you would want to live for the next 4 years.
Start with something like location. If you like nature and don’t mind being in the middle of nowhere, think Dartmouth or Cornell. If you want a more suburban small-city experience, think Brown or Princeton. And if you want to be in the middle of a city, think Yale, Harvard, Penn or Columbia.
What other characteristics are you looking for in a school? Do you want small (Dartmouth), medium (all Ivies besides Penn/Cornell), or large (Penn & Cornell)? Do you want heavy core curriculum (Columbia) or none at all (Brown)? A good greek scene (Penn, Cornell, Dartmouth) or something else to replace greek life (residential colleges @ Yale, eating clubs @ Princeton)?
So to answer your earlier question for what Ivies you have a chance at, I think it’s more important for you to think about which ones you truly want to go to. Then come back and ask CC about your chances at those. You can even start looking at other top schools in the USA besides Ivies to match the criteria you come up with - there are lots of academically rigorous American places that are not as hard to get into as Ivies yet can offer just as good of an experience. Good luck, you’re going to go somewhere great!
