how about seminar? they are frum but i dont think they are judgemental or too strict or maybe meohr. tell your school you want to go and if they cant help you maybe you could try to call the seminary yourself.
no its not too late, a girl in my class applied last week and got in! tell your principal that you want to go and im sure your school can arrange an interview for you. good luck!
I’m going to Nachlas. and Moderators I think you should delete yogibooboo’s comment. Bnos Sarah is a great seminary and many girls wish they could go there.
