I've said this on other threads that I've yet to meet anyone at a top school who's actually had the BBVA loan. Everybody I know has help from parents, grandparents, re-mortaged, savings, etc. There are the odd few people who are from some serious wealth, but they're definitely in the minority, and these super-rich tend to be from the middle-east.
I can't imagine the BBVA stopping their loans having much of an impact at all, I honestly don't know anyone who's funded their integrated training this way. There seems to be a big stigma connected to the top schools that everyone is walking around with a £100k BBVA loan, paying-back £1200 per month, but I assure you this isn't the case. The BBVA will have little impact on the number of people going to the likes of CTC, CAE and FTE.
