Don't go to uni - fly. By the time you have got everything done a couple of years will have passed. Then instruct for a couple of years and by that time the job market will be on the way up.
Do a degree if you loose you medical. Then you will be motivated where as at present you piss it up the wall as you would rather be flying. And your 2:2 from Derby university will be equal with every other "Blairs Britain of medicoracy" graduate and not be worth the paper it written on. You will also have too much student debt to fly.
