The so-called good and bad actually come from our standards. Every child has his own characteristics. We should not define it as a poor student just because of poor grades. What we want to cultivate are children with good qualities such as true integrity, kindness and sincerity
that they can have a positive and optimistic attitude towards life, know how to respect themselves and others, have their own interests, have a sense of responsibility, confidence, tolerance and magnanimity and will lend a helping hand to others when they need help.
We should not take grades as the only measure of whether a child is good or bad.
