Keepittidy,
if you are genuinely interested, then first off Moray college run evening classes in all sorts - I did Higher English there yonks back, and compared to the schoolwork of the average RAF course civvy college courses are a complete breeze - turn up now and again, make sure you turn the coursework in on time and it's a piece of p. I did the Open Uni for donkey's years - the RAF subsidises that, work in your own spare time, with a week at a UK Uni in summer for some courses (as duty). That CAN get heavy going - many a time I sat on detachment looking at the sunshine while opening a book, but if ou want to do it you'll manage it like a huge number have before.
The RAF is pretty keen on improving the educational quals of its members - and you don't need the Jengo to okay stuff....it'd be a brave Jengo who was prepared to go into print to stop you gaining educational qualifications.
