If the max hsbc will loan someone to do OAAs course is £50k, how are people getting £100k in debt? Seems the max debt will be £50k, the rest will have to be saved up before starting. The repayments will be around £500-600 a month. If the student managed to save £50k before starting I would assume they had a good career to go back to after they finish, thus should be able to service the £600 a month. If it was given by rich parents, then as long as the student lives at home, they can make the repayments even on minimum wage.
On the other hand, training modular, paying for each lesson at a time then perhaps taking a smallish loan for the IR you could find yourself stuck trying to pay off the £200 a month loan on top of a mortgage and family.
This is why the mod/int debate will never end and threads like this are pointless. You can make either method look better just by choosing your words carefully.
