My son just started Pre Nursery at a private kindergarten and he's already having homework (writing alphabets) and spelling (ant, apple) plus chinese words (on flashcards) to recognise.
They are tested every Wednesday.
It's a 2.5 hour daily program, not full day childcare.
I took him out from CCC cos they focus more on 'looking after the kids' rather than academic teaching. & since I have a maid, it was easy for us to change over cos no issues with childcare arrangement
