<p>I have heard that Carnegie Mellon is excellent in comp sci. as well as the arts, but that there is a pretty big divide between these two communities. I haven’t heard anything about economics.</p>
<p>Maybe you already know this, but at Wellesley you can take classes at MIT and I think Harvard. Obviously, it’s not terribly convenient (about 45 minutes away by bus if I remember correctly.) But you could take a class or two from world-leading economicists at MIT while still enjoying the excellent teacher-to-student ratio at Wellesley.</p>
