I have problems with the University Life
All the Services are looking for people who can make the best of the situation they find themselves in - if you are having problems "with the university life" is it likely you'll find something big to whinge about when you are in a blue suit?
My advice - man up, get the degree and apply to the RAF in your third year. Leaving now, with the high probability of not getting past OASC will leave you up the proverbial watercourse with no means of propulsion.
