The student pilot reported that during landing on his third solo flight, the approach to the runway was high and fast, and that during touchdown, the nose wheel touched first resulting in a porpoise.

During the porpoise, the airplane drifted to the left and the pilot elected to abort the landing. He advanced the throttle to full power, which increased the yaw to the left. The airplane exited the runway to the left, impacted a ditch, and nosed over. The airplane sustained substantial damage to the left lift strut, empennage, and fuselage.

The student pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
