internships+grad school

<p>I´m a freshman at university of pennsylvania. I'm majoring in econ (in the college), and probably a minor in actuarial math. I just finished my fall semester with a 3.78. I was just wondering how competitive is this GPA for internships at the likes of goldman sachs etc? And if I decide to go to grad school, what minimum GPA should I aim for to get into a top school?</p>
