hi..
idk if this is the right school site but i have also been looking for schools near where i live moti nagar or kukatpally but i think this may be the site for kennedy im not sure but i hope it helps.
Kennedy High School-Hyderabad
site for sliver oaks if u haven't seen much -
SilverOaks School
my little cousin goes there and i went there to check last summer when i went to india for summer vacation the school was huge and really cool but also my another cousin which is his older brother got kicked out if you fail in that school they would really kick you out of that school.. so its really strict. but i just noticed they have a lot of activities like swimming dancing acting singing band and fun festivals and sport. it looks fun but really hard to keep in that school unless your child can really concertrat on work also and get good grades that would be fine for her then. well best of luck my mom said i won't pull it off joining that school is very hard for me since i have been living in us for 8 years and finally thinking of staying in india next year.. but i don't know so wish me luck also. haha thanks hope it helps bye
