Just looking at some figures, I came up with this:
50th percentile tuition: £8,600/$13,700 per year (classroom-based, undergraduate)
Average living cost: £9,000/$14,350 per year
So around $28,000 per year. Not to mention other costs to actually get into the country, such as
medical insurance
travel insurance
student visa
baggage
travel
phone
television licence
et cetera
