This is for my nephew who will be in 2.10 years by next academic year(2018).Can you suggest good schools with CBSE syllabus around Nanganallur. Parents are looking for a school which gives equal focus on extra curricular activities too. They have shortlisted these schools

1)Chellamal
2)Modern( Looks like kid will not be eligible as they admit only kids above 3 years)
3)DAV Adambakkam
4)PSBB Millenium
5)Saraswathi Vidyalaya

Any other schools to consider?
