Preparing for CMO (China Mathematical Olympics) requires the following preparations:

Make a study plan: make a detailed study plan, allocate the daily study time to different math subjects, and ensure that there is enough time for review and practice every week. At the same time, it is necessary to arrange rest time reasonably to avoid excessive fatigue.

Mastering basic knowledge: CMO examines basic mathematical knowledge and skills, so it is necessary to master basic mathematical knowledge in junior and senior high schools, including algebra, geometry, probability and statistics. We should be able to use this knowledge flexibly and solve some complicated problems.

Brush questions and mock exams: preparing for CMO requires a lot of practice and mock exams. You can improve the speed and accuracy of solving problems by brushing questions, and be familiar with the examination forms and questions. At the same time, a mock exam should be conducted to simulate the real exam environment and pressure and improve the coping ability.

Expanding mathematical knowledge: CMO examined a wide range of mathematical knowledge, including elementary mathematics, algebra, geometry, probability and statistics. While mastering the basic knowledge, we need to expand our own mathematical knowledge and understand some in-depth contents, such as calculus and linear algebra in advanced mathematics.

Pay attention to thinking training: CMO examines students' mathematical thinking ability and problem-solving ability. Therefore, we need to pay attention to thinking training, learn to analyze problems, find laws and explore solutions. At the same time, we should be good at summarizing and forming a systematic knowledge system.

Adjust mentality and maintain self-confidence: It takes patience and perseverance to prepare for CMO, adjust mentality and maintain a positive attitude. At the same time, you should believe that you are qualified and don't give up because of some difficulties.

In short, preparing for CMO requires comprehensive and systematic preparation, including making plans, mastering basic knowledge, brushing mock exams, expanding mathematics knowledge, paying attention to thinking training, adjusting mentality and maintaining self-confidence. Only by making full preparations can we achieve excellent results in the exam.
