The student pilot reported that he was performing a solo flight and was on an extended final for runway 22L with the intention of performing a full stop landing. The air traffic control tower requested that he change to runway 22R. The pilot maneuvered the airplane for the requested runway and was cleared to land. He extended the flaps to 40 degrees on short final. He stated that he should have extended the flaps earlier because of excessive airspeed. He said that the airplane passed over the runway numbers at an airspeed of approximately 75 knots. He closed the throttle and the airplane floated for an extended period of time. The main landing gear then touched down on the runway surface and the airplane bounced. The pilot held pitch attitude and the airplane touched down on the runway surface again. The right wing then lifted upwards and the airplane veered to the left. The pilot applied brakes and right rudder, and the airplane departed the runway to the left. The airplane then collided with a ditch, collapsing the nose landing gear and causing substantial damage to the firewall.
