<p>I have had a fair bit of conversation about this, so I'm aware of the basics - i.e., I realize the grad school game is different from the undergrad game, realize teacher recommendations are huge, research is good, and such things. </p>
<p>For math grad school, I've heard lots of things about the likes of Princeton and the other really elite schools. What seems to make the cut?? There are a very, very few people enrolled each year, right. So is it usually one really famous professor who makes it...is it papers...is it just being exposed to exceptionally serious math and showing promise as a sophisticated mind?</p>
<p>I have it from a Berkeley grad student or two themselves that papers aren't that common in the pure math world for undergraduates, unless they're not really pure math papers. Even the most brilliant professors kind of say what one can do in undergrad in terms of research is heavily limited - even for advanced undergraduates.</p>
<p>WHAT MAKES THE CUT? Is it ULTIMATELy random to a degree like undergrad admissions? I hope not! I have some years, so please comment.</p>
