@NROTCgrad Alright after major research, I may have unfortunately (for me as well) disproven what you claim. According to statistical analysis by Poets and Quants, shown here for Stanford Business School (just an example, you can look up similar analysis): http://poetsandquants.com/2012/05/30/top-feeder-colleges-to-stanford-b-school/2/
A majority are top-ranking prestigious institutions.
