Human Factors
I was flying on my first solo flight.  I had just completed my first pattern and landing when I had the excursion.  Everything looked fine until I touched down and lost directional control.  I attempted to use the rudders to bring the airplane back to centerline but the oscillations got bigger; and that is when I exited the runway.
A Student Pilot; on first solo flight; reported losing control during first landing; and exiting the runway surface.
