Passed with 75%. Not proud about that, just plain lucky.
Congrats on that!!! You passed and that's what it's all about, pretty damn sure that nobody will every ask you on that again!!!
As already mentioned before,
time management is critical in G-NAV given that one has to answer 60 question in 120 min, that gives you 2 min per question (and not a second more). So don't get stuck with a single question, trying to get it figured out, it'll catch you in the end when your running out of time and too many unanswered questions remaining!
One key to success is knowing how to work the computer (CR-3/5 or whatever) in and out, forward and backward, since this will make about a good quarter of the G-NAV exam questions (Dead Reckoning)! The other part of the questions will focus on In-Flight Nav, Charts (scale calculations) and Basics of Nav (each making up about a quarter of the exam questions) and don't spend too much time on Magnetism & Compass!
And don't forget, in the end it's all about passed or failed - 75 will be your lucky number!!!
