Here is my impression of the other three you mentioned – THIS IS ONLY MY OPINION from what I’ve seen
Masores Rochel: (Big 100- 150) So I don’t know tons about this seminary but from what I’ve heard and the girls I’ve met this is my impression. It is very hard. Textual learning and a lot of work. Rebbetzin Tarshish is supposed to be unbelievable. It is a very in town seminary with an in town feel but it’s also quite yeshivish. They are pretty into their clothes and some would call it quite jappy. There is supposedly a lot of girls who had really good jobs in school and are quite popular. It’s supposedly a pretty high pressure place when it comes to peer pressure. If you are the type of girl that is not scared off by that dynamic and is the popular, smart in towner who comes from a pretty yeshivish background then I would say go for it.
Binas: (Smallish – 60, 70 girls) It’s a new seminary so this is all speculative. The girls who I know who went there give me the impression that they are really nice girls but not especially open. I would call it the atypical, yeshivish girl who is insistent on having a mind of their own. The girls there also have personality, they are pretty loud – definitely not boring kids. But they are not the type to sit around and talk about culture. They are trying to be academic but I’m not sure what the work is like.
Bnos Sarah: (Largish 90-100 girls) Bnos Sarah’s reputation has blasted over the last few years and it has become one of the hardest seminaries to get into. It has an extremely sweet and friendly reputation with girls who care about each other and have little peer pressure. It is very academic with a lot of work and classes in Hebrew but I think the learning is more like BJJ with a bit more memorizing and inspiring, beautiful classes then ultra intellectual and self taught learning. It is a very out of town environment with little to no peer pressure and girls who are very open minded but not ultra modern. The girls are in a few words: open, extremely sweet, spiritual and smart. It has a lot of work but it’s supposed to be interesting stuff
