the sole purpose for me to post here is that I found there are quite a few misunderstanding on this board about schools' situation/reputation. I don't want some new MBA students discover the fact first several days when they arrived the campus. What people here in the U.S. think about schools such as HBS, Yale, MIT, Wharton, and Columbia is kind of different from the impression I got here.
I am not an alumnus or student of any of the school listed above, so my opinion is not that obviously skewed.
