In addition, it should be noted that BrainCo's concentration course is helpful to improve children's attention and concentration, but it is not omnipotent and cannot replace other educational measures. If children have difficulties in learning or behavior, parents are advised to seek professional psychological counseling or help from educational institutions to find more suitable ways to help children solve problems.
