Will i be expected to pay the money back in one lump sum?
As far as paying back the money you've borrowed is concerned, the interest on the loan you will probably be paying monthly and you should've already allow for the first three months of that when applying for your loan. As far as the capital is concerned, that's another matter, you can probably arrange to pay this off by stage payments, which means that you can pay it off a chunk at a time which is not quite so daunting.
