I looked at going to school in the U.K. as well. It is incredibly cheaper, far cheaper than most schools in the U.S. It is also considerably harder to get into, unless you are looking at schools in Scotland. Apparently, Scottish schools are more open to accepting U.S. students because the American school system is very similar to theirs, while it is drastically different in England. It's always a good idea to get into contact with an admissions counselor. I would highly recommend doing so if you're serious about this possibility.
