Mommy studied @ a PAP Kindergarten when she was a young girl... During the period of time she always felt unbalance why the students in the other room always having art lesson another batch of students always having outdoor games. After all these years of thinking she finally realise that there should be more then 3 classes in her school. Now she is wandering how many classes did the school have.
