How likely is an application by transfer?

<p>I got into a few schools, but I hadn't applied to CMU, even though I had intended to. What I'd like to do is go to Pennstate for a year and then transfer to CMU. I already have an associate's degree, most of which I believe will transfer to PSU, and I'd like to pursue engineering; my highschool stuff is likely good enough to go, but I have no idea about applying as a transfer, except that you are compared to the incoming freshman class if you are an undergrad. Can someone offer me advice?</p>
