CAIS

May I ask the parents of current CAIS student, if I want to get into CAIS, do u think it is easier for my girl finish local K2 then proceed to CAIS prep class or finish local K3 for their Grade 1
I personally believe the longer time she stay in current KG she can have more exposure to chinese and she can also try to interview for other DSS, however the places for Grade 1 would be tighter than prep class? THX!
