last year there were 28, this past year (my year) there were 60,- so I really don’t know how many girls- but i think they want about 40.
on rosh hashanah and yom kippur we were in school- you could get permission to go out if you have family- they find places for you to daven- but you have to pay for your seat- some meals will be given in school and some you can eat out if you want- or you can also asked to be placed somewhere to eat- and succos first days we were in school- we had our own sukkah and some of the faculty ate with us- and we also ate by their houses. second days you can go out- but the dorm was open if a group of girls wanted to stay in! Hope all this helps!!!
