Lt.Ub,
the matters of the heart usually take much time to trully reveal themselves. Thus, while it is the case that my heart is oriented towards cornell, I am taking the time to thoroughly inform myself so as to convince myself that, more than Penn, Cornell is the right place for me.
What I meant by "culture" of a specific school has to do with the fact that two institutions deemed peers of each other by virtue of their academic reputation (i.e Ivy league) each bears its own intangible identity. For example, Cornell med is known for assembling a culturally diverse class. Also 50% of the fourth year class go abroad. These two factors, in my opinion, says something about the ethos of the school. Within this same frame, Penn might be said to be a more research oriented place, as reflected in the amount of time allocated for "scholarly pursuit" and the like.
In all, there is always a subset of traditions that mark the uniqueness of a school, even when the latter is classified within a broader group with "peer" institutions. (I am in a real rusht to catch a movie, I hope this post makes some sense). Thank you, though, for your honest and helpful insights.
