I passed first time, no minors... what can I say?! :P
My first test was postponed due to snow, so when I actually got to take it 2 weeks later I'd kind of calmed down a bit I think (I failed my mock really badly, as in multiple majors badly haha, so I'd convinced myself I couldn't pass, but the extra calming time really helped)- just keep in mind that it's not the end of the world if you fail, and keep positive: you'll be fine!
Also be nice to the examiner! Can't hurt to be friendly...
