The mummy was just asked if she was a working mum or not.
And all the questions for the kid were very simple like name, age, fruits, colours, fish, counting, fork / spoon,.... pls point at daddy, mummy.... pass sth to 校長........ give me five....
I believe the questions were all simple and the atmosphere was quite good..... don't worry.
But I just dunno about the selection criteria as there are such limited seats with so many applicants.
