1) For most selective colleges, they'll be living in a different neighborhood or different city, in a college dorm instead of their house, with classmates instead of parents & siblings. So almost everything is different.
2) Sure. Environment has both short-term and long-term effects. So a fraction of the environmental effects wear off. I dunno what the fraction is, but when you do the regression to find the weighting of SAT test score and adversity score that best predicts college achievement, it should find the right balance.
