From a real world pilot: The landing: learn how to fly a proper traffic pattern...proper entry (45 degrees to the downwind) square turns, constant speed, NO hard turns on final esp at lower speeds. Aim for touch down marker 1,000 down cross the threshold at about 65, fly the plane into the flare bleeding off speed so that the airplane stalls (stops flying) when the rear wheels are about 1' above the ground. You were too low and too fast on the final when you had to over correct to get back to the centerline of the runway.
