Please help your child analyze the reasons. Is it because he can't, or doesn't understand what the exam is, and he doesn't write where he can, with a playful attitude, or because the teacher doesn't understand what it means after reading the topic?

If you don't understand what an exam is, tell your child that when the teacher looks at the requirements, he should write down what he knows as required. Try to let the children know about the exam at home.

If the child can't do it, but for mental problems, you have to take exams to make up for the child.

Also, it is illegal to say that primary school students only have one exam each semester, that is, the final exam, and nothing else is called an exam, which is called an "exam". :)
