I was also in the same situation, where location is not a constraint, as i am shifting from Bangalore to Hyderabad. I looked for schools in and around Gachibowli, Kukatpally, chandanagar, Financial district. Finally, we zeroed on Samashti international school (kollur) and also we decided to stay near Nallagandla (around 10Kms from school). This is a pure CBSE school. You can visit the school and decide.
Thanks for reply .. Do you know the fee structure in including transport .
Please check the fees structure.
