There are several schools in and around Sholinganallur, some good, few average and some bad.
I would recommend that you research the following in the order of preference-
Really Good schools
1. Babaji Vidhyashram - CBSE Affiliated
2. PSBB Millenium - CBSE Affiliated
3. Ramana Vidyalaya - CBSE Affiliated
4. Barathi Vidyalaya - CBSE Affiliated
5. Ayyapa Matriculation - State Board
Not so good
9. sacred heart
In terms of excellent teachers, infrastructure and value for money, I would say Babaji was my first preference. Both my children study there....however I looked around quiet a lot before I put my kids there and hence the full list.
Good luck with your child.
