If you are going to have to make any flights out from home to Edinburgh keep that in mind as well... Those sure add up quickly. Also, you will need a bus pass over here... it isn't terribly expensive but it is something you will have to get unless you want to buy a car.I came up with something similar: about $236K for four years. Here's my basic per-year breakdown:
tuition: $44,919 (assuming exchange of $1.61 per GBP)
rent: $5,796 (non-campus)
cell phone: $773
I worked from weekly estimates provided by a cost of living section of the UofE site. This doesn't include a budget for "fun stuff" or travel...
