To add to my earlier thread, we are looking for 10th grade admission in Chennai.
Were you able to get any information?
You have almost dozen schools in Velachery area coming under CBSE category. All being in almost same level of fee structure. But if you like to take upon International Schools you dont have one such in that rador. We have one in Guindy though, Hindustan groups which is good in terms of academic as well as extra curriculars. If not you need to relocate to Besant Nagar / Thiruvanmayur side as you have good stretch of schools in OMR / ECR. But if you ask about their standards only one or two meets the average level, we are yet to reach IGCSE / ICSE level as in other Metros.
