I’m surprised about that quote from Yale too, but no doubt that Penn is preprofessional, and if you are in Wharton or an Econ major there is not way out of it.
Are you a First year? Is this First semester?
Are you lower income? (Many top privates have 50% full payors or more, so the income social issue differential is not going to go away if you transfer to say, a top LAC.).
