What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was on first supervised solo flight. After second solo landing aircraft slowed too quickly prior to turn off, pilot added power causing aircraft to speed up more than planned for. Pilot pulled power to idle and realized they would be unable to make safe turn, applied brakes and stopped at taxiway edge. Choice between turning back for runway or taxiway, pilot chose taxiway to not cause runway incursion. Applied power to make sharp right turn, aircraft rolled into grass. Propeller struck taxiway light - damaging propeller and light. Pilot reduced power to idle again, stopped aircraft and contacted ATC. Attempted again to move aircraft in grass but wouldn't move. Aircraft was then towed to ramp from grass area for mtx inspection.
