Excuse me, do you want to ask the question "how to write a child's careless comment on the exam"? Comments that can be written in this case are:

1. After reading the exam, I was basically satisfied with my child's study. But we need to get rid of the old habit of carelessness. There are several things that should not be wrong, and that is carelessness. We will cooperate with the teacher to catch up with his study progress.

2. Judging from the children's papers, their professional achievements are excellent. Compared with last time, there is no retrogression or progress. I hope the child will continue to work hard and go up a flight of stairs.

The total score of this assessment decreased slightly, mainly because the children were careless. I will help children get rid of this problem and ask teachers to educate more during school.
