1. First of all, keep up with the review progress and requirements of the school teachers, take all the problems seriously, and complete the school's homework requirements.

2. Secondly, in the review process, I found that some knowledge points are a little lacking and can't be ignored. We should study textbooks and homework carefully in time, and then find some extracurricular exercises, and practice about 20 to make up.

3. Finally, it is more difficult to review the knowledge system of function, similarity and roundness than the school teacher takes the students to review comprehensively, because the school teacher usually reviews it based on the actual situation of 70% students in the class.
