No, but the odds of things turning out the way she intended are just barely good enough at a top school that it might be rational.

I agree it may not when compared to a top school for MBA or Computer Science. Still it opens more opportunity such as consulting in Big 3 or your boss has more contacts in pharma industry so there is a chance you will get some entry level opportunity in big pharma or biotech startups. But if you are from a middle tier state univ where you boss do research on "sleeping habit of frog or pink fluffly bunnies" then you are out of luck.
