What do you mean by, 'is being rejected the end?' Are you young enough to back to the RAF and try again? The Navy and AAC have higher age limits, especially the AAC, which gives you time to change, improve maths and practice a bit. (I've done OASC, and I recon simialar practice would make the tests easier). What about Nav, have you considered that, or was that also ruled out by the aptitude tests. Have you decided to give up on the Forces, and go for a civil flying job?, in which case, you're in the same boat as most other people here. You can pay to do the GAPAN tests, and re-consider your ideas after the results.
It was a bit foolish to hit the Stella, a pint probably wouldn't matter too much, but if you got wasted ...
