Emory Internal Medicine - Primary Care Track

I am a first-year medical student at the Medical University of South Carolina, so perhaps my inquiry seems a bit premature to some. But I am very interested in internal medicine, namely Emory's internal medicine primary care track residency. I am fairly confident I want to do internal medicine (although I am certainly open-minded about the process, and realize I could change my mind once I start clinical rotations). I definitely want to do private practice, hence my desire to pursue an internal medicine residency with a primary care track.

I am interested in hearing more about how competitive this specific residency program is. I am aware that internal medicine is not considered extremely competitive, but the fact that I am intersted in Emory probably makes it a much tougher residency to get. What kind of board scores would I need to be competitive for this program? How much do grades during my first two years matter? What can I be doing now to make myself a competitive applicant?

If anyone can help me, I would greatly appreciate it. Thanks in advance.
