Everything you need to know (unless the rules change) has been put down here over the 2 years or so. Try reread the thread and you'll feel that confidence coming. As always, you'd be better off stressing on accuracy if you aren't fast enough (or if you're too nervous or sick or something). Whatever you do, get it right. Same rules will apply in the psychometric.
Old Airport North-last time I remember, coming from Msa road that is, there was a detour with a tiny sign that said "Airport North Road". Noticable, you just follow that until you see a hangar out distant with the kq banner. You'd be better off using private transport but if you're using public (34? or 33? Not sure) you might want to get out a lot ahead of time. Good luck!
