To bb9931 and other applicants, did you contact professors/PIs at the institutions where you are applying? It is crucial that you communicate with people you might want to work with and let them know that you are excited about their research, give them a brief rundown of how amazing you are, and let them know that you applied or are planning to apply and that you would love to know if they will have an opening in their lab in the Fall (or whatever term you are applying for). This serves to make the professor feel that you are particularly interested in their research and not just applying to the program because of the cachet (or alternatively as a safe school, etc). Make the professors feel flattered and wanted. You LOVE their research and want to work with them and only them...you only applied to the program because of their research that you read about in their papers A and B. Its a dating game. And if some guy came and said how he admired X, Y, and Z accomplishments of mine and thought I was an awesome person and also demonstrated that he had desirable qualities himself (minds out of the gutter now!) and asked if I would go out with him, I very likely would say yes. Flattery works.
