Hey dont worry about it. It happens to all of us. When I did my private, i had no problem for the oral, but once i got on the plane I froze, I was so nervousness, I was drenched in sweat.I messed up my soft field landing because I was rushing and couldnt wait to get over with the flight. To this day I still get nervous on checkrides but nothng like the first one; I just drink some hot tea, go over all the procedures and flight in my head and hope for the best! good luck!!
