Frenzy, I am assuming that you have spoken to the teacher already, so what is the response? I know you are most likely trying to handle this on your own, but perhaps one of your parents should get involved with letting her/him know how critical it is to complete the evaluation.
We had same problem with one teacher and she did not budge until I got involved. I understand it is a delicate balance between pestering and nudging, but I also think that USNA will not hold it against you as you really have no control over whether or not your teacher completes the evaluation. Keep pressing forward.
