Check Aspen Montessori. I send my kid to Aspen Montessori house in Khajaguda. When I joined him as 2.5 years old, my idea was to keep him in the school for an year and move to a standard school with pp1 admission. However, I am so impressed by their teaching methods, I decided to continue him in the same school till UKG.
It's a cozy place with 1:10 teacher kid ratio.
Best part is, my kid loves his school.
I would definitely recommend it. I think they have a school van for kids coming from alkapur. Check it out.
