I'm a student at an average state university without a phd program in econ. My GPA is average (3.4 overall, 3.8 in Econ and 3.1 in Math), but improving every semester. My weakness is in math as you can see, but its also in the lack of math classes. I have about a year and a half left on my undergrad, and I am thinking about going an extra semester to take more math classes as I have only completed through diff eq. I should be able to improve my GPA in math by a few points. My university doesn't have a very strong econ program and am finding a lack of research available. I am wanting to get into a top 50 school, the higher the better of course, what would be some advice to help me with that goal? Thanks!
