The expense thing isn't completely accurate, in a best case scenario you'll be spending £12,000 over the 2 years and realistically it'll be £18,000 or £20,000. Either way you have to fund it yourself which is frankly unrealistic, the most I've seen a student make in a year who didn't have an internship in IB or their own business is about £3,500. The rest of the money you would need to get a graduate loan for which obviously doesn't carry the nice repayment terms of the graduate tax/student loans. You would be better off doing an M2, I'm not sure if they're offered outside of France but it'll mean you'll only have to fund one year and you'll have an extra year to raise funds. There's also your bog-standard year abroad route.
