I am impressed by the number of people waitlisted. I think B schools abuse too much of this practice, it should be reserved to a limited number of cases that are truly borderline between admit and ding. I really do not see the point of having hundreds of people on waitlist. B school already accept more student that they can take because they anticipate the aprox. number of people that will go somewhere else.
I also don't like this "please send us anything that can strengthen your profile" when you already worked so long and spend so much money in your GMAT, Essays, School visits etc.
It's just my opinion...
