don't panic. I don't think they really scan kids in this way. Sometimes the kid may not be able to tell you the whole process. And highly possible, kids try to avoid telling you the questions which he could not answer. I guess every kid should be given equal chance. My boy told me that there was no English nor Putonghua questions. However there were a lot of interactive exercises which i think they were funny.
according to last year, if the teacher ask question that mean your kid will have higher chance, those who only watching TV & drawing, lower chance. I believe they had scan all the application.
