A few things: Beyond making your application stand out, you will have to thoroughly and adequately answer Why Michigan? What does UMich offer that Michigan State does not? (and being higher ranked is not the answer) How do you know this after just one semester at MSU? I am not trying to be difficult, just want to make sure that you have clarity in your thinking and can articulate those thoughts.
I would also encourage you to attend a Transfer Tuesday session at UMich. Good luck.
