<p>My brother chose Berkeley over Brown and Princeton as a physics major.
I am choosing Berkeley over Yale and Cornell as a pure math and earth science double major.</p>
<p>If I were you, I’d go to Brown. Seeing that you want to look into international relations, I’d think that Brown would provide a better general environment for such a major. IR is existent at Berkeley too, but Berkeley, at least in my mind, seems like more of a engineering/math/science school.</p>
<p>Both Berkeley and Brown are great schools. I’m sure you’ll enjoy the school you end up going to.</p>
