I was tested by this examiner for a BPA exam and failed.  The chest straps were placed around my chest hard enough that I couldn't help but be aware of my breathing.  I told her as much and she shrugged it off. I wasn't nervous, confessed to and answered every question with honesty. After a few hours of charts, she said that I was deceptive, and I recieved the failure email about 30 days later. 
Fair enough, huh? I believe that I would've been a great asset to the agency based on my knowledge and idealism, but it doesn't matter now.
