May be the reply is late but go for billabong high if distance is not a problem for you its much better in terms of child care and parent interaction
yes Billabong Malad would be a good option to consider
Billlabong is a good school. However, look at the distance from your home to the school. In nursery its best to look at options nearby. I am in Kandivali E, so I put my child in Kangaroo Kids Kandivali (E) , it is one of the best standalone preschools in the city and is affiliated with Billabong. So, now when my child passes from Sr. KG she can directly get admission to Billabong High! You could perhaps try for the same - see if there are any kangaroo kids centres around. They are the preschool arm of Bllabong.
Is it really possible to take admission in Kangaroo kids for nursery etc and then get a chance to get admission directly in grade 1?
Can anyone confirm this?
