dont take anything for granted until you have your first day of turning up at your unit after getting out of the college.
the age old quandry of wherever you want to go, you will get the opposite.. its both NATS and murpheys law you know. at least it was moons ago when i went through.
then there is the question of validating, fail that and you could be catapulted to the somewhere you may not want to go.... If you just want to do the job and would happily go anywhere.... thats the spirit!!!
all the best and enjoy!
