A cram school can help children check for leaks and fill gaps, because children sometimes don't pay attention in class, and as a result, some knowledge points are not learned, and even some students can't keep up with the teacher's learning progress, which leads to more and more backward learning. At this time, a cram school can review key knowledge for children, help children understand the knowledge points they don't understand in class, and thus continuously improve their academic performance, so the training class can really change their academic performance in some aspects.
A cram school can calm children down to study. In fact, sometimes parents send their children to training classes just for the teacher's supervision, because some children always watch TV or play games when they get home. If children can at least settle down to study in cram schools and have teachers to supervise them, they can still play a certain supervisory role, gradually change their laziness and stimulate their learning initiative.
I don't think cram schools are omnipotent, so parents must treat them rationally. If children get excellent grades and can learn independently, they will not enroll in cram schools at all, which will only delay their study time. If the child's grades are not good, or even serious, parents can enroll in cram schools for these specific subjects. Don't sign up too many cram schools for your children. After all, learning is a natural thing, so we must pay attention to the combination of work and rest.
