The 3 exams were principles of Fright, Performance and Systems and Powerplants. I have gone through and through these exams in my mind's eye and have remembered a couple of questions that I definitely screwed up.
Case in point - what is a zener diode? I know this and it should have been a no brainer but like a fool instead of answering voltage regulator I put down voltage rectifier.

I guess my brain was on holiday. Don't know why I would put down such a silly answer.
Not all is dark clouds though, here and there I found a silver lining. The question about flying at the same Mach number at a higher flight level tried confusing me (and almost succeeded as I was so rattled by then) but I think I managed that one okay.
I had not run across that one in any of the feedback, and arguably it is not really a performance question so I presume if one had it wrong it is grounds for a protest. Am just hoping I don't have to worry about these results ever again after next week Wednesday or Thursday.
