Moving from Chennai to Delhi

Hello,

We are planning to move to Delhi shortly. We have not yet decided the location but thought of finding a school for our daughter - 3rd standard and look for a house near by the school. please help me finding a Good school. Will appreciate if the locality is around South Indians to start with.

Also one big issue - she has chosen Tamil as her second language for 1st and 2nd standard. Though basic hindi is taught, she knows only to read the basic consonants. She doesnt know to read words and all. how big will be hindi from 3rd standard onward if she has to catch up. (She is very good in studies) is it advisable to start some Hindi tuition now itself?

Also, her current school closes by April mid, learnt that schools in Delhi starts by April beginning. will she get an admission at all? Should we pay a visit once to place her in school?

Please help!!
