Let me fish inside the town first and then I will give a try then.
I know a person who can help me in this, he is in the ruling party at the moment
Good. But make sure that he is really up the ladder. Because here inside the city (for some schools like PSBB / Chinmaya / DAV) almost 50% people are coming with recommendations.
I believe in equal proportion of studies vs games vs extra activities.
The problem I have is, which board is best or good
Definitely not Metric, because Amma has screwed it very badly (via Samachir Kalvi) and that is the reason why there is huge demand for CBSE and ICSE.
Personally, as I am from CBSE I prefer that. But ICSE or Montessorie are equally good or better, provided you are ready to spend say 30% more and also remember to continue in the same board (as each board has it's own pace and if board is changed then the Kid may feel the pressure)
