As Dirty Sanchez says go and visit different sqn and go flying with them. This gives loads of benefits:
a, it's a good tick in the box at OASC when they say what have you done to find out about your chosen NCA trade, it shows you have got off you ar$e and done something
b, you can get some really good flying out of it (I flew the low level heli lanes in London in a Puma, and it was outstanding), and if you are really luck you can come and fly on a mighty Herc (K of course)
c, you may find out you hate it and its not for you
d, you may find out you love it and it will give you that little push to try a little harder when things start not going you way
and
e, its better than free because the air force will pay you travel cost etc. (which I suppose is free before anyone starts getting clever)
I did it a few years ago and it is the best thing, air force wise (just in case my wife reads this), I have done.
Also girls love flying suits as we all know
Get your head in the newspapers and get a good idea of what is going on in the world and in the UK.
All the best M8
