I was told I failed because I was tapping my foot and it was considered counter measures. Now I explained to the instructor it was simply a nervous twice nothing more. Then he began to give me the third degree about how he's been doing this a long time and seen a lot of things and he knows what he saw. I continued to plead my case by telling him I'm nervous and it was nothing of the sort. Then he began to pressure me into believing that my only chances to continue was to write an apology letter to the  Dept. and ask for forgiveness. So I did under duress. Which at the end I told him I still believe I did nothing wrong. It was the last step in the process and was nervous. At the end he said he was writing a report about me trying to use counter measures to beat the test and I insisted that he was wrong it was a nervous twitch and nothing more.    I'm trying to request a retest but not sure if they will.
:( 
If anybody has any advise that would help I would be grateful...
