Yeah so £33,000 is about $51,000 (using the current exchange rate....the dollar is stronger lately than it has been!). And we do have the lowest tuition rate of all the UK schools. This cost difference is probably made up for during the time you'd spend living in London (years 1 & 2 of the 5 yr program or only 1 yr for the G&T program.)
Its definitely cheaper than going to most places OOS and some IS (Penn, Tufts, Cornell...the private schools). Moving isn't a huge expense, most people are bringing mostly clothes and its free to check your first suitcase. I sent a couple of enormous boxes over here (one with a large comforter in it) and each cost me around $120. Living on campus in London isn't too bad cost-wise, definitely cheaper than most places in London. Rent for the clinical years (in Potters Bar area) is well priced...probably comparable to a lot of similar places in the US. Living in London on a budget can be hard but there are many things here that are either cheaper or comparable to the US.
