I went straight from Public School to RAFC Cranwell as a Flt Cdt. Did a year, then 4 at university (it should have been 3 but I enjoyed the UAS too much!), then back to do a Graduate Entry course.
Glad I did both; 'real' Cranwell was quite hard but fair. University opened one's eyes somewhat though - and I really appreciated that.
On balance I reckon that a year out, followed by 3 years at RAFC including proper BFTS training with degree accredited military studies and academics would be top banana. Plus a bit of pine pole carrying and marching around, of course!
Fat chance though.....
