I went to BY intensive seminary in 2010.
AMAZING sem.
There were different types of classes, it appears they try to be good about giving you your preferences. My class was a beautiful mix. a class of 32 we had about 18 out of towners including toronto, Lakewood, Monsey, 5 towns …
The class had a few chassidish kids, some very yeshivish and many very mainstream, and 2 Sefaradim. It was an unbelievable experience. The motto gotta be “accept and respect” and then you are A ok.
The dorm is amazing. Not that I stayed there but I practically lived there.
