I'm currently a Junior at a Jesuit, liberal arts university. Due to Hurricane Katrina, I have been forced to attend three different universities during my time in undergraduate school. However, I am finally back to the university that I had every intention to attend when I graduated high school. So far, I have completed two semesters at this university with a 3.85 GPA and a 4.0 GPA in Physics (I have a transfer transcript of a 3.5 GPA as well, but this does not factor into my overall GPA). I completed research as a freshman (in the area of astrophysics), but I have taken a larger interest in theoretical physics, including special and general relativity. For about a year, I have been working one on one with a well-known theoretical physicist in an attempt to better understand special and general relativity and (hopefully) complete research in these fields. I am currently studying for the GRE Physics and regular GRE, and I am planning to go ahead and take the GRE Physics in April 2008 and November 2008. At this point in time, I have my sights set on Ivy League schools and other universities, including UC Santa Barbara, Indiana University, Berkeley, Standford, U Washington, U Chicago, MIT, Cornell, etc. With my current qualifications, what GRE scores do you think I would need to keep these schools as options? Also, if I were to obtain these GRE scores, would I currently have a good chance of acceptance at these schools?
