PhD in business economics/strategy. How do I get in?

<p>I'm a sophomore at Washington University and I currently have a 3.44 gpa. I'm a major in economics and will probably double in finance. I have only taken math up to calc 2, but am good at math and am relatively confident I can succeed at harder classes.</p>

<p>My dream is to get into the Financial Economics program at MIT, but also would be ecstatic to get into Harvard, Penn, Stanford, Cornell, Michigan, Columbia, or NYU.</p>

<p>I'm not sure exactly what I want to focus on, so my target school might change, but most likely I want to focus on applied microeconomic/game theory and/or business strategy.</p>

<p>I am pretty confident that I can get at least a 700 on the GMAT, given my past testing history, and am pretty confident I can get my gpa up to at least above a 3.5.</p>

<p>The admissions statistics to these programs are, well, discouraging. Any advice on what I can do to get accepted?</p>
