What should I tell my parents if I don't do well in the exam?

If you don't do well in the exam, first of all, you should have a good attitude, especially when you scold your parents, try not to talk back, don't let your parents think that you don't care, don't care, and you'd better make sure that you will make progress next time (don't say that you did well in the exam, because the definition of progress is different, and progress is easier to write than doing well in the exam). Uh-huh, you can consider crying in front of your parents. Anyway, parents usually love their children, and tears are in their hearts when they see them.
