British Mech Eng Student - Year in the US

[Fletcher19]

2nd year atm and basically i am thinking of doing my final year in the US. I would like to finish my course here but it looks like a load of my mates are going to drop out very soon and although it would be easier to just stay and finish in familiar surroundings with the rest of my mates it has inspired me somewhat to go away for a year.

My department runs exchanges with

University of California
Georgia Institute of Technology
University of Illinois at Urbana-Champaign
Pennsylvania State University
Rensselaer Polytechnic Institute

tbh i am not really concerned with georgraphical location. which of these are considered the better ones?

Also somewhere without too many skinny arse frat boys but not just full of nerds either
