One thing I will say, although I think this has been a great thread topic, is that the frequent posters on the other side of CC I find to be of a very different mindset than those of us on the BS side.
Many of their threads induce chest pain and I find myself regretting even going over there. The more objective, concrete threads (describe school X, visit days, etc) are ok but the subjective ones are much more difficult for me to read.
I think BS provides a different insight and also a different “want” out of college. Also, the BS application process taught us so much about admissions in general, I feel like we have a step up on those who are brand new to the concept.
I would place a bet that the vast majority of those on the college transfer threads came from home and of those, the majority came from public schools without the resources to provide tailored college counseling.
