To be fair, when you arrived SMM, the class already started, so maybe the teacher was in a hurry? My friend's son studied in SMM and he said his teachers are very nice. Another friend of mine attended the interview there and said that the teachers were all kind and polite.
Thanks for your advice.......
I also would like to keep my boy at kcs, coz he really loves to go to school....right now..... hope that the P1 challegue is smaller than I thought....
