I am almost done with my junior year at a top 15 liberal arts college. I'm majoring in physics with an overall gpa of 3.5 which I hope to pull to a 3.6 by graduation. My physics gpa is about 3.85. I am interested in attending a top school to do medical physics. Duke, UChicago,UW-Madison, and UC-Berkeley would be my top picks. I'm expecting 2 awesome recommendations and one thats good but will probably not rave about me. I've done research in physics and will be doing medical physics research at Duke this summer. I also intend to write the GREs this summer. What do you think are my chances of getting in? Will it help if I write a thesis? I wasn't going to because none of the professors here do research that is in anyway related to medical physics. I've also done a lot of stuff outside the classroom, plenty of leadership and community service. I know this isn't really looked at for graduate admissions but I figure It can never hurt me. How do I improve my chances of getting in? Are these schools even the ones I should be looking at?
