I finished my undergrad last year with a B.S. in Biology and a B.A. in Philosophy with a minor in Applied Math. Right now I am in an M.S. program for Geographic Information Science, which I should be finishing this year (graduating May 2013). From my studies and general interests, I've decided that I want to move towards Math. I am a little undecided between Applied Math and Statistics, but despite my background in Biology I am not that interested in narrowing myself with Biostatistics. Here's some info about me:
GRE: 780q/580v/4w
Undergrad GPA: 3.92
Grad GPA: 4.0
For math classes I've taken up through multivariable calculus (calc 3), differential equations, intro to linear algebra, and a couple statistics courses.
From what I've seen looking at even top grad programs, their minimums are pretty much what I've taken, but is that really all that I need? Will it just be expected that my first couple semesters will be taking more "remedial" classes to catch up with everyone else, or should I go back and get a bachelor's in Math? It would take me about a year (6-8 classes) to get one at my first institution.
Also what level of school could I expect to get accepted to? I have very high GPA's, but they are at somewhat lower institutions compared to what I see people post on here. Would I have a chance getting into Top10 schools? Top20?
Thanks in advance for any advice!
