Transfering to UW Chances?

<p>I'm currently a freshman student at Iowa State University looking to transfer to University of Washington-Seattle for my sophomore year. I'm currently majoring in Civil Engineering but will switch to Petroleum Engineering (not offered in Iowa State but offered in UW). It's my first semester and I'm taking 12 credits, with 4 completed credits from APs. My GPA right now is a B (midterm). What are my chances of getting into UW?</p>
