Hi Nanny, I went to Seminar a few year ago, and it was amazing! The girls are more out of town than in town. Academically, it is hard to say, cuz I don’t know what you consider hard. But I was in the honors track and I definitely worked. The classes are amazing and even now, after a few years, I keep in touch with some of the staff.
Sorry, I don’t really know much about Ateres so I can’t really compare it for you.
