Low GPA but High ACT?

<p>I took the hardest course load available at my school, I'm an IB diploma candidate and I'm in the top 10 percent of my class but I have a low GPA its around 3.4, (4.2 weighted). However, I have a high ACT, I got a 30 on my ACT, and I'm a URM (hispanic). I'm also in 4 clubs and hold 2 leadership positions and I have around 500 hours of community service. Do I have a chance at NYU or University of Chicago? How about some Ivy League maybe Cornell, U Penn, or (and I know this is a really high reach) Columbia?</p>
