ANW1988 - I think more then the fact that you failed in house aptitude test, the real issue is are you really prepared for what is to come?
Do your OAA, get into £90.000 debts, pay your TR another £20.000 and then go and get a job earning £1200 a month.
Now if you have done that calculation, and then still think OAA is the BEST option out there, you should have an additional look at the Modular route, which will set you back around £40.000 from 0 hours, and you will still have money to pay for your TR, because no company at the moment will pay for your TR.
I would rather question your sensibility!
Go figure that one out £110.000 vs £60.000 in cost, what you prefer?
