not sure about AQR, but OAR I believe is the Officer Aptitude Rating, FOFAR I think is your Aptitude rating to be a Flight Officer, and PFAR is your Pilot aptitude. All those are used for the ASTB test given by the Navy, only the FOFAR and PFAR are used by the Marines. I'm sure somebody out there could elaborate or correct me if I'm wrong. I know that for the FOFAR, PFAR and AQR the highest scores you can get are 9/9/9.
