I was recently admitted into MIT for undergrad. I know GPA is not the only factor, but do you all know around what GPA I would need to earn at MIT (I hear that there is grade deflation) to get into a biology or biochemistry Ph.D. program at a school like Stanford, Harvard, Yale or Berkeley? I am still deciding whether I should do my undergrad there or at a university with a lesser known reputation because the ultimate goal is to go to a good grad school.
