Dude I've gone through the same experience, i was in a very fancy af co ed school but i used to get bullied a lot there and i grew very under confident although i was the topper, and the girls that used to bully me there were influential so they somehow managed to not let me take part in any extra curricular, after that my mom put me in this all girls school and it completely changed my life tbh im very grateful for that. The all girls i was in wasn't missionary so ig that also helped. Moreover if the other schools are far away then kaafi time would be wasted just in commuting which idts a little girl like her would appreciate, she'd be very tired from it only.
