<p>Erm, wait badman, are you deciding on an undergrad school with the hope that you'll be going to grad school after college? Or are you trying to decide on a grad school? It's not clear to me... </p>
<p>If you're heading to undergrad, I don't know about philosophy, but at least in a lot of sciences/math (bio, physics, chem, math), a lot of the top schools will NOT take their undergrads back for grad school because "academic incest"--staying in the same place for multiple programs/positions--is generally frowned upon. People prefer to see that you've gone somewhere else, branched out, been exposed to a different school's way of thinking, etc. If you're thinking about undergrad, that's something you might want to consider if you're certain you'll be applying to grad school.</p>
