The reason for this is the following：

1, school delay service is mostly "form". At present, under the impetus of the national double reduction policy, many educational institutions have closed down, and schools have also carried out delayed services accordingly. However, many schools do not have clear plans and goals when they carry out delayed service, and the learning effect of students is not ideal. At this time, children should be sent to cram schools to improve the weak links, otherwise the school's delayed service is just a waste of time!

In many schools, the delayed service is teachers' lectures, while in some schools, the delayed service is students' homework. I don't think this has helped students solve the most fundamental problems. Delay service should be targeted service. For example, if students can't master math well, they will organize the students who are not good at math in the whole grade and systematically review what they have learned recently.

Today's work is finished today, and the total amount of knowledge that students can receive every day is fixed, so they should review it in time that day. Therefore, if the delayed service is just a form, it is better to let the children go back early and go to the cram school.

2. Delay service cannot digest knowledge points one by one. Children's poor academic performance is due to poor foundation. To improve your grades, you need to supplement basic knowledge. However, the delayed service is aimed at most students and cannot be comprehensive, which leads to the poor effect of delayed service for children at school.

In order to help children consolidate and digest every knowledge point and improve their academic performance, parents are advised to take their children to remedial classes for improvement. Because the learning task of the remedial class is very clear, that is, to check and fill the gaps and improve the children's grades. Compared with the school's delayed service, the study arrangement and plan of remedial classes are more conducive to the improvement of children's grades.

Therefore, if you want to improve your child's academic performance, you can send your child to a remedial class to improve your performance without applying for delayed service, and then go to school for delayed service.
