I am an IMG and living in the US now. Since my husband's doing his residency in IM, I am thinking of not getting into clinicals. I am interested in doing MPH. I am confused and I dont know how and where to start looking? I have checked out a number of univs and they require GRE. So could you tell me about how to go about and how much time do I require to prepare for GRE? When do you think should I apply for the programs and how?
