I wouldn't send any girls I had to the school I went to because the emphasis was too academic - the year I finished it was the top school in the state (the boys at our brother school got in trouble for being beaten by a bunch of "giggling school girls".
We could do any extra-curricular activity we wanted, but it still wasn't a holistic approach.
If you weren't good enough academically you had to undertake a "lower" program that didn't count towards the school score.
Also because it was so expensive only a very narrow range of girls went there - the fathers were all doctors, lawyers, etc etc etc. Mostly white, with a couple of Asians, noone from the sub-continent.
Very restrictive socially if you didn't want to hang out with "snobs" all the time.
DH went to a catholic boarding school so he went to some dances with some of the girls from my school. After he met me and found out what school I went to he was very surprised because everyone else he had met that went there was so different to me....
I think it was a great school if you were brilliant academically, but if you were only mediocre, another school with a more rounded approach would be alot better....
We are not going to enrol our boys at the brother school....even though my dad went there...
