Seshank, I am student of Bala Vidya Mandir, Adyar. Would like to tell you that by no means it is a dummy school, neither is it a very strict one. I've had a chemistry teacher in my class who would help solve JEE Advanced level questions. They are pretty supportive of students aspiring for IITs also. I have one friend in my class who had to miss all 3 revision exams the school conducted, since he had to do JEE Prep(He got 99.7 percentile) as well as attend the NDA SSB(Almost Selected for NDA) and still was encouraged by the school.
Coming to your other question, I don't really think that you would be knowing my faculties since I study in adyar, whereas you study in a different part of the city
