<p>Hi!! well i am doing post graduation in mathematics from a very reputed college of delhi university..i just wanted to know how to go applying for a phd in universities abroad and that if a GRE is a must for all the universities..also that if its compulsory to have a publication at the masters level,in situations that i dont have any which univ should i be aiming at??</p>
<p>I think most people on these forums are probably undergrads and most likely won't be of great help to you. I would recommend contacting you college's advisor or perhaps an advisor of one of the colleges you are interested in applying to in order to find out more information. From what I know, the GRE is basically a must have for graduate school in the US. I don't think a publication at the Masters level is necessary, but it would probably help with admissions. Again, an actual advisor would probably be the best source of information for you.</p>
