I agree, I an an undergrad right now and have just been accepted to all teh grad programs I applied to. For what its worth, I applied to the design field, so it is a little bit different. I had a decent GPA, 3.5, but what made me stand out where amazing letters of intents and an outstanding portfolio, well given that I have had no formal trainging in art. I never even took the GREs but went ahead and applied to programs that required it, and they accepted me without the scores. In the end, a decent GPA, killer portfolio and no GREs got me into five schools, one of which is Ivy League and the other is the top art schoot in the nation (risd), which I have since accpeted.
Also, dont limit your options, if you have a dream to apply to harvard, apply, sont assume anyhting is out of your range, otherwise you will regret it and always wonder what if. the worst they can say is no
