You could try Unicent in Nagole ,
Mount Litera Zee School in Hayatnagar.
You can also find Panineeya Mahavidyalaya in VV Nagar, Dilsukhanagar and Oakwood International in Satya Nagar, Kothapet. The Intl tag is only for namesake.
Akshara International and Edify World School in LB Nagar are good schools. Fees is a bit high in both these schools.
If budget isn't a constraint, you could prefer Akahara Intl followed by Zee School, Unicent, Panineeya and Oakwood.
Kindly check the middle school in Edify.
