One thing I noticed was a certain challenge with spelling that was evident in your thread. (Ok, I can understand if it was a bad keyboard or screen that you were using. It seems you have a recessive N). If the spelling hastle is a persistent one and you have not yet decided where your career will take you, I would pursue a career in the airlines where the spelling issue won't matter.
Good luck with it all Mate!
