Premise: Unconventionally gifted kids, who didn't get top grades in high school or who don't have perfect SAT scores, stand a better chance than they do elsewhere of getting in--and of being presented with the highest level of intellectual challenge.

Hypothesis: Here, kids who are gifted despite not getting the best high school grades or SAT scores are more likely to both get in and be challenged intellectually as best as possible.
