In the last month of the math sprint, we should strengthen the review and summary of the previous rounds. Students who have established the wrong problem set and learning card can strengthen the review and induction of the above knowledge at this time. Students who have not established these tools do not need to spend a lot of time sorting out the wrong questions at this time. They can take out the papers from previous exams and check them directly. At this time, the focus of review is no longer to emphasize the possibility of a topic, but to master a knowledge point. To strengthen the mastery of knowledge points, there is a skill, that is, put the previous questions together. For example, look at the series of the last big question and mark the missing points in the college entrance examination outline. The highest loss rate is the weak link of your own knowledge. If the candidates are short of time, parents can do it for them, sort out the materials and make targeted reviews for the candidates.
