Making up lessons to improve grades is secondary, and mastering learning methods is the key. What is the problem that your child can't learn math well? You can ask elite teachers to analyze the children's learning situation. If you are not interested, then the teacher's teaching method is not suitable for your children. If you can recite all the mathematical formulas, but you don't understand the meaning of the topic, it is the child's language problem. Find the root of the problem first, and then talk about whether to make up lessons. It is useless to make up lessons without good grades, which will only make children tired of learning!
Make-up lessons that don't pay attention to learning methods are hooligans!
