Thought this might help if the BA scheme through CTC is similar to how things were during my time with CTC.
Loan of £60k was available for the full cost of training. A foundation course cost circa £5k and you could have that on top of the £60k if you wished. In addition for those that had no financial assets you could also get a loan of £10k to cover living costs.
So 1 loan of £65k and 1 loan of £10k if you needed it. This was when the course was covered by HSBC and I've no idea what BBVA do in terms of financing but if BA are willing to provide the security then I see no reason why you can't do something similar.
Yes I know prices (not costs!) are different now but you get the idea. Good luck to everyone
