I would recommend my kid school (Apollo international preschool). It is very clean. And the teacher are caring and loving. Cirriculum is very interesting. Enrichments included. Fees very reasonable.Low ratio. Provide good/nutritional food. In house nurse for ifc too. Complimentary dine take away for ifc.
