Hello, I have accepted an admit for fall 2008 at a certain university for phd in physics. even though this is a fairly good university, it was not my first choice (I didnt get admitted to my first choice). My problem was that i did not have phsyics gre score and i was solely admitted based on my profile. My undergrad background is also of engineering. can anyone tell me if it is possible to take a transfer to one of the top universities once you've already started your graduate studies at an other university? also, will it help much if physics gre score and some of the physics grad courses are added to my profile?
