I was accepted to a top-tier west coast program, to which I never in my wildest dreams would have imagined that I'd get in. One thing is certain - GREs are not as important as one might think and you shouldn't waste too much of your valuable time on studying to this atrocious test. Instead, I would suggest, for future readers of this thread, to focus on your letter and writing sample. Have as many people as possible read them. Try to be as creative and memorable as possible. If you're invited for an interview - that's great, cuz it gives you an opportunity to persuade the faculty of your strengths, thinking process and personality. During my interview, I actually realized that I really fit in with the department so.
Another important thing that I have learned from this experience: most students who apply to a Ph.D. program have an MA or some kind of equivalent degree. If you are fresh off your undergraduate studies, make sure to supplement this relatively disadvantageous position by improving your essays, or even by physically visiting the different programs and professors that interest you the most. It might prove so valuable and make you memorable as well as allow you to see things from another perspective - one that is not so much available from a distance.
Good luck you guys!
