Why U of M?
I transfered to U of M from one small college in North Dakota. The reason i chose U of M is that i thought the city size just was perfect for me. Too big cities seems crazy to me. And U of m has a very good reputation among the universities in the US. When i came for registration at the university, the people were so friendly. I am very glad that i chose U of M.
About the weather, it wasn't a big deal for me since i came from a pretty cold country :)
