Yes, mothers from BK stated that there'll be a change from 5 days to 3 for the PM class cos HKPS wants to expand and have more classrooms. HKPS is one of my preferences but now I really have to think. The environment won't be good for learning when the school is under construction...
I heard Think is good for K1 to K3 but not sure about N1.
Different : K1 to K3 - english base
N1 - teach mother tongue (cantonese) & teacher turnover rate is pretty high (just heard from other ppls, not sure if it is TRUE. Recommend to do more research! BK mums, pls share if you know)
