Think it's looking a bit clearer thanks to your help and lots of searching and enquiring. The medical shouldn't be a problem- it's the same i had to be an RAF Reservist, my eyesight just isn't quite 20/20 for military regulars.
I've found a professional studies loan which might work out if i also keep working for about a year too to ensure i have enough savings to complete a Bristow 1yr course- plus this is the soonest i can get a place there.
Any further advice is very very welcome and much appreciated as always.
