Your chance of getting into Harvard? Almost nil, from what I understand. Probably better of staying in Sweden.. although if you can get into one of the big schools in the states that would obv. be the best option (Harvard, Yale, Princeton, Stanford, Wharton -- once again chance of getting in is fairly low)

Also, from what I recal D.E. Shaw only really take PhDs in Math / Stats / Physics. The only way someone with something less would be getting in is through some decent work experience.
