So I'm interested in getting an MS in Statistics and here's my situation: I did relatively well on the GRE: (V: 168, Q: 165, AW: 4.5), however my undergrad GPA was 2.97 at a state school. I only took one true math class, Calc I, which I got an A in. I majored in Economics. I'm 4 years out of college and about two years ago I found self-discipline. My perspective and work ethic has done an about-face in this period and I've seen tremendous results in my life. Now, I want to get an MS in Statistics, but my low GPA is obviously an issue. Here's my tentative plan: take Calc II and then linear algebra this summer/fall at local universities (Villanova/Penn). I'm confident that I can get two A's. I'm hoping that doing so would lend credence to the narrative I will present to schools, as well as fulfill the prerequisites of most schools. My question is, even if this all goes to plan, will I be able to get in anywhere? Say, assume I do well on the GRE subject test as well. It will be painful spending the thousands of dollars on these two math classes, but if doing well can reasonably get me a spot somewhere, then it'll be very tempting. Thanks for any advice
