My advice is, if it all goes pete tong, just stay calm and fly the aircraft. On my skills test I failed to identify the village the examiner had asked for. I was uncertain of position, but managed to get a fix by using two VOR radials. I was convinced I had failed but, to my astonishment, the examiner passed me because he was happy that, even though I'd screwed up the nav, I'd remained calm and flown the aircraft, and managed to get things back on track.
Very best of luck with it.... You may be in that Cirrus sooner than you think
