In general - NAPS/USNA do not withdraw appointments except under exceptional circumstances. The most notable exceptions are medical DQ before arriving for PS or prep; serious criminal activity; or a significant change in academic performance. Getting a speeding ticket or a "C" or "D" in a class your senior year is not, in normal circumstances, going to get an appointment revoked.
