The student pilot reported that while on final approach to the runway, he was high and slipped the airplane to lose altitude. As the airplane crossed over the runway, he pitched the airplane forward to prepare for landing. The student pilot stated that he "felt the [air]plane losing forward momentum and added throttle to compensate." The airplane landed hard, bounced back into the air, and began to drift to the left. As the student pilot attempted to abort the landing by applying full throttle and reducing flaps, the airplane landed hard and exited the runway to the left. Subsequently, the airplane impacted a ditch, which resulted in structural damage to the rudder, left aileron, fuselage, and engine firewall. The student pilot reported no mechanical anomalies with the engine or airframe prior to the accident.
