“[Bnos Sarah] is really hard to get into – you can really only get in with push. So if you want her in, prepare to have many phone calls made.”
Speaking from personal experience, this is not true. If you deserve to be in Bnos Sarah, you will get in without making a single phone call. It could be that some people use protektzia, but that’s true for every seminary. Most girls get into Bnos Sarah on their own merit.
