Hey guys. I'm in third (final) year of my B.Sc. in physics. Have done/will be doing courses like Relativistic QM, intro to QFT, GR, condensed matter, etc. I am interested in astrophysics and cosmology and have done some work on it under a prof during vacations. But, my CGPA is on the lower side (7.1/10). I want to do PhD from a good place (say, Harvard?), and chances of getting in there with this score look bleak. So, I thought I'll do M.Sc. first and then dream of such things. Can anyone suggest me some places which might be accessible for me? Thanks.
