What would the teacher say if he failed in the exam and asked his parents to go to school?

I am a teacher. The purpose of inviting you is to strengthen communication between teachers and parents, ask about children's family situation, talk about children's performance in school, discuss how to teach children well, and find countermeasures against problems such as children dozing off during the day, parents asking children to go to bed early, writing untidily, and supervising children to practice copybooks.
