If primary school students have similar problems of inattention, we must set good rules for them. If parents don't have time for self-study, they can try to stay in class at night with senior professors of upper control education, and then give one-on-one tutoring, so that they can get used to it in one fell swoop.

Primary school itself is not difficult. If you have a correct attitude and do the questions carefully, you will get high marks.
