My son is 0712, he wasn't able to speak in interviews last year as well. He managed to get offers from HK Ling Liang Church KG, North Point Methodist KG and Victoria KG. Finally we accepted Victoria as it is closer to my home. He was rejected by SC, well I knew that would happen as he couldn't talk AT ALL.
My son attended Victoria playgroup, so the teachers know him well, that's why he got a place I guess... my husband was Old Boy of HK Ling Liang Church KG and North Point Methodist Primary School...
