This is a question which i faced 7 years ago.. I am just telling you what I did and what I felt is the best option... each school is special in its own way...consedering the primary school section, Birla,Ideal is considered good.. but what i did was to put my child in to the private school where they prepare the child for the actual school into first grade... here the child has fun, learns the same portions as the kg classes in school and also get to go to sleep a bit longer as these school timings are only around 8.30 am.

My child did his kg1 and Kg2 in these school and i put him for 1st grade in School. he had no problem taking the tests ment for grade 1 admissions. and is still doing well..

hope i was able to give you an idea.
