The final exam is coming, and the children's grades suddenly drop a lot. Should I go to Huandu Consulting or other counseling institutions to sign up for classes?

It is of little significance to attend remedial classes. Choosing courses as a proper guide for teachers is useful, but it has little effect. Only by letting children try to clarify formulas or basic common sense can they improve their grades. Maybe your child is influenced by other reasons, and finding out the reasons is very helpful to improve his grades.
