hmm it may due to not enough english teachers ar. It operated since last yr, only have PN, K1 (don't know having K2 yet).. may not have sufficient NET for running 7-8 interview groups in 1 time slot.
my son is studying in Kornhill K1, English and Putonghua class. There are 3 teachers, one American English teacher, one Mandarin teacher from China and one local teacher who will only speak in Cantonese if the kid doesn't understand. I'm quite happy with the teachers there.
