Totally agree... there is a misunderstanding about the problem. In fact, the education system is not flexible enough to adapt to the children's mental age. And, therefore the education system as it is designed is causing damage to a group of students. A solution might be delay 1 year to enroll the children. Another solution is to subdivide the admission to 2 or 4 times per year or ideally grouping students by maturity level and personalized education.. but I guess the cost might be prohibitive.
