PS, since you ask about prestige, I would say my friends who either are English or have been living in England for a long time, seemed to ooh and aah slightly more over my child’s unconditional to Durham. However, when I asked the college counselors at two different (both prestigious) private day schools, in our area of the United States about these schools, both of them seemed more familiar with St A’s. Both had sent more (American) students to St A’s. So I think this depends on who you tell. I think both are excellent schools and I wouldn’t give one moment of thought trying to predict my audience’s reaction to my choice of school, anyway your audience could change over time. I think you can have a great experience at either.
