How difficult is it to get into a masters program in pure math if one is a non-math major? Does anyone know which masters programs are particularly friendly or unfriendly to non-math majors? I'm currently a philosophy major at a liberal arts college but by the time I graduate I should have completed Calc I,II,III, Proofs, Linear Algebra, Diff EQ's, Group Theory, Complex Variables, Real Analysis I, Ring Theory, and a Putnam Seminar (with all A's). My overall GPA is 3.43 but should go up by the time I graduate. I'll also be graduating in the Fall semester, so I'll have a semester in between to take more math courses as part of a post-bac program (I'd like to do this at UPenn). What are my chances? I'm just worried that I wont get accepted to any graduate programs because of my major. I'm willing to pay, so that's not an issue.
I'm willing to hear any tips you have to offer.
