@avaluxe:
Nobody can take the achievement from her, but you have to analyze different perspectives as well which do not apply to all.Even though all universities write about 'equal opportunity for all'....the fact is that there is much more competition among male students than females.If that was not the case, Cornell wouldn't have started 'special' initiatives for hiring woman grads and encouraging the female alum to 'seek out' female from their locations in the first place.If you want further proof regarding this you may check out their website.
On the other hand its not about African-american thing here!

.There are much less female population going in for MBA than males, so even if they seek women with comparatively low scores it shouldn't raise false hopes in a male aspirant that the same would also be in his case.B-schools always try to maintain the aspect ratio in their classes.
I have also seen the same being done by many other Ivy schools.
