Every parent whose child's grades are not good will have your reaction, and you will be angry in your heart, but the follow-up behavior should not bring your emotions to the communication with the child. It is necessary to find out the root cause of children's unsatisfactory grades: it is because of carelessness that they make mistakes in the topics they can do; Or because I didn't understand the meaning of the question, I made a mistake; Still can't do it at all; Or the method of doing the problem is wrong, so that it is too late to finish the problem. You should carefully analyze and communicate with your children. Discuss with her the reasons for her poor grades. Then the right medicine can fundamentally solve the problem.

1, it is because of carelessness that the topic that can be done is wrong; Then we should correct her bad habits.

2, or because I didn't understand the meaning of the question, I made a mistake: do more exercises to exercise her understanding ability.

3. Still can't do it at all; Listen carefully in class, review carefully after class (urged by parents), do more exercises, or ask a tutor.

4. It is still the wrong way to do the questions, so that it is too late to finish the questions: in the exam, if there are too many questions, you can choose multiple questions from simple to difficult, do the questions you can do first, and do the difficult and ambiguous questions last. There is no need to waste too much time on difficult questions, otherwise it will lead to some questions that could have got high marks and lose points because of lack of time.
