I know I’m a bit late to this, but the last post was correct in saying that inter BS transfers are not too common. The majority of the students that know who have transferred into the place I will be graduating from did it for athletic reasons (thus, had support from the coach in the AO). I only know one that I know who wasn’t an athlete; they were coming from a smaller yet quite selective BS to a larger setting with more opportunities, and they did it going from 10th to 11th.
