I have been accepted to the the theoretical physics program at Uppsala University. It ranks around 60-120 in the world for physics and astronomy. I know these rankings aren't the best metric to determine how good a program is, but it gives me an idea. I want to know how good the program is for theoretical physics, I'm interested in string theory and physics beyond the standard model. I'm pretty sure I can get into better universities, is it important that I get into the "best" university that I can? I'm thinking about applying to University College London and The University of Edinburgh.
