I know this post might be too old for your consideration but I definitely recommend Birla Public school. My kids go there and they love it. Ramuk, I disagree with you about Dr. Mohan Thomas. I have met him personally and he seemed like a very polite and erudite person. I cannot imagine a better chairman for a school than one who is well educated himself and listens to the concerns of parents (I have emailed him multiple times and he has sorted out my questions/concerns immediately).
