The solo student pilot reported that the airplane landed hard on the left side of the runway. He added right rudder, but the airplane did not respond quick enough, so he added power to perform a go around. The airplane exited the runway to the left, impacted a ditch, and the nose landing gear collapsed.
He added that, after the accident, his instructor told him he could have used the right brake to aid in directional control.
The airplane sustained substantial damage to the fuselage.
The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
