Most people believe that children should not be put into primary schools under 7 years. However, my personal experience, both my children entered primary school at the age of 5 years and 5.5 years. Nevertheless they can follow the lessons at school well even got a high rank in his class. In my opinion, if the child is ready to enter elementary school, seen from the ability and desire of learning is strong. Why not, we provide opportunities for children for better learning.
