My son attends the nursery class there. He was in the other campus (Dorset) for playgroup. I personally prefer the Dorset campus because I feel it is more spacious and there is more space for cars so pick up and drop off is easier.
In terms of Mandarin, I'm quite impressed by what's he's picked up so far. I don't speak any Chinese but he can speak very simple phrases, knows basic colors, fruits, animals. Also, they've started phonics and I was quite surprised when he told me that he learn the letter D and listed doctor, dinosaur, and several other items that start with D. My son is just shy of 3 yrs.
Yes, the tuition is getting ridiculously high so we'll be moving over to a local kindy. Also, some of my friends complain that the administration is bad and the school is very commercial.
