Grasp the key points and break through the difficulties

In view of the new situation and new characteristics of the college entrance examination, we must boldly change and innovate in preparing for the exam in the later stage of senior three mathematics, pay attention to thinking methods, problem-solving strategies and exam-taking skills, break the order of knowledge structure, break the old-fashioned math exam-taking strategies, truly learn methods, improve students' comprehensive ability and exam-taking skills, and calmly embark on the road of reviewing and preparing for the exam.

1. Solve minor problems and prevent overtime work.

We know that the multiple-choice questions and fill-in-the-blank questions, which occupy half of the national mathematics test papers, are naturally the "big names" in the three types of questions (multiple-choice questions, fill-in-the-blank questions and analytical questions). Whether these two kinds of questions can get high marks has a great influence on the mathematics scores of the college entrance examination.

Therefore, it is very necessary for candidates to have regular quantitative and qualitative training in the later period. It is necessary to strengthen the training of multiple-choice questions and fill-in-the-blank questions, and strengthen the training time to avoid the phenomenon of "saving time and making mistakes" and "losing points over time".

2. Return to basics and reorganize

In the mathematics college entrance examination paper, four basic questions are basically finalized, namely, one of three choices, trigonometric series, probability problem and solid geometry. These big questions are the main positions for scoring college entrance examination questions.

Looking at the previous candidates, quite a few students have low test scores. They didn't lose points on difficult questions, but on basic questions, which led to unsatisfactory final exam results.

Therefore, in the later review process, we should try our best to return to the basics and reproduce the context of knowledge and basic mathematical methods through combing the knowledge. Make sure to do a certain amount of basic problems every day, and constantly increase the training of basic problem solving, so that students can do this part of basic problems correctly and completely and get full marks.

3. The key question is often "interview"

In the later review, if you want to get the maximum benefit from the review in a limited time, you must focus on key issues and be able to do "focus interviews".

For mathematical functions and derivatives, trigonometric functions, series, solid geometry, analytic geometry, statistical probability and other major plates, we should focus on reviewing key knowledge and be willing to spend time and energy.

In the review process, students should be able to find out whether there are defects in their knowledge or problem-solving ability. If defects are found, it is necessary to re-integrate the relevant contents according to the methods and ways to solve the problem, and form the latitude and longitude map of knowledge and methods.

4. Post-review is by no means a simple and repetitive process.

We should find the best fulcrum of grading-the quality of group questions, grasp the "increasing points"-the basic questions of college entrance examination, grasp the "key points"-the key modules of knowledge, break through the "difficulties" of knowledge-analytic geometry and derivatives, and leave no "blind spots" for reviewing and preparing for exams.
