Any review of PCF Sparkletots Preschool @ Cashew Blk 183?

I have a friend who sends her 2 kids at Cashew Bk 183 branch. She has intention to withdraw her kids from the school as she feels that her kids learn very little from the school. The teachers in the school use 'independent learning' approach to let students to do their own works and without supervision/necessary guidance. Thus, my friend has to send her elder girl for additional english and chinese enrichment classes and she feels very stressful to coach her kids after work.
