please help me out!!
You could try schools in Narayanguda/ Himayat Nagar / Abids/. King Koti. These areas are close to Barkatpura.
You could try Oxford Grammar School ( CBSE) in Abids. Most of the schools in Abids follow State Board and a few like George's Grammar and St Josephs follow ICSE.
You could have a look at Howard Public School& Vasavi Public School in Himayat Nagar and Rishi Public School in Basheerbagh. All these schools follow CBSE.
Other leading schools like BVB , P Obul Reddy, DPS etc are quite far and mid term admission would be difficult.
