<p>I think you’re looking at this the wrong way. It’s not so much where you go to undergrad that says where you’ll go to grad school as much as it is what you do in undergrad. Sure, you may have a better chance if you went to a private or public Ivy, but that’s only because I would assume that you are a motivated and successful student. If you go to a less known public or private university, you may have to work a little harder to prove that you’re just as educated as one of those Ivy league graduates. Looking at what intellexi posted, you can see that people from all types of universities are now studying at one of arguably the best business schools in the country. Pick the undergrad university you feel most comfortable at and take advantage of the opportunities that are offered. If you’re cut out for an ivy graduate school, then it will happen. If not, then you are part of millions of people who didn’t get an ivy education and will probably still do just fine.</p>
<p>So the answer to your question is yes, you can go from a public university to an ivy university. Ivy leagues don’t just pick their grad students from other ivies, there are a bunch of people from other universities that are part of the grad programs too.</p>
